Despite advancements in dentistry, the reality of tooth loss persists, particularly among geriatric and medically compromised patients. This vulnerable population will also suffer from functional decline and age-related pathologies. Thus, preserving and restoring teeth and oral function will be crucial, and the loss of teeth significantly hinders chewing ability because prosthodontic treatments cannot fully restore masticatory performance. It’s worth noting that the retention of natural teeth is linked to a longer life expectancy. This presentation will introduce the role of growth factors and dental lasers in periodontics and how different specialists in dentistry could work together to keep teeth and implants for life.

We have developed a bovine bone xenograft (OMB) doped with antibacterial lipoic-capped silver-nanoparticles (AgNP), for alveolar ridge preservation after tooth extraction. In 4 sheep, mandibular premolar teeth were extracted; each also received two 8.5x4mm deep circular defects in the femoral epicondyle of both posterior legs. Sites were filled either OMB, OMB+AgNP, BioOss® xenograft or left unfilled, and covered with a resorbable collagen membrane. Two sheep each were euthanised after 8 and 12 weeks. Samples were analysed using non-demineralised resin-embedded histology.

Results: OMB+/-AgNP demonstrated equivalent bone fill to each other and to BioOss®; all grafted sites showed more bone fill than un-grafted controls. Mandibular socket and femur sites were comparable. Results were not statistically compared in this pilot study. Conclusions. Both modified OMB BBXs showed equivalent results to commercially available BBX (BioOss®). The addition of AgNP did not impair bone healing. This pilot study supports progressing to larger-scale preclinical trials.

Periodontal treatment in post antibiotic era will incorporate significantly reduced, if not elimination of, antibiotic use for the management of the periodontal diseases. In their place, the development of novel antimicrobial and, importantly, inflammation modulatory biologics, that can be incorporated into sophisticated or simple delivery systems will be used as adjuncts to conventional periodontal therapy. The use of these adjuncts would be based on current understanding of the pathogenesis of periodontitis and the central role that inflammation plays in this process. This should not diminish the rational use of antimicrobial (non-antibiotic) agents as well.

Treatments could be made on the basis of a personalized approach to specifically target the microbial biofilm, the inflammatory response, or both, depending on the clinical findings and individual features of each case. Thus, a more holistic approach to management of the periodontal diseases will evolve and move our treatment focus from a mono-therapy anti-bacterial approach to one that considers more of the underlying causes and ramifications of periodontal inflammation.

In the future, the use of antibiotics will become redundant as viable alternatives for their replacement become available. This, together with novel local delivery vehicles will forge a new future in the post antibiotic era.

Hereditary gingival fibromatosis (HGF) is a rare disorder characterized by a benign, non-hemorrhagic, fibrous gingival overgrowth that can appear in isolation or as part of a syndrome. HGF usually begins during the transition from primary to permanent teeth, other than disrupting the eruption of permanent teeth and functional derangement of the dentition, it can have a negative psychological effects to a young patient due to impaired aesthetic.

As it does not resolve spontaneously, both periodontal and orthodontic aspects need to be considered which may involve multiple surgical intervention and orthodontic movement which prove to be challenging. This lecture will discuss the Periodontic-Orthodontic management of a clinical case of HGF covering the various surgical approach, timing of extraction and orthodontic movement.

Objectives:
– Understanding the clinical characteristics of Hereditary Gingival Fibromatosis (HGF).
– Discuss management of HGF involving periodontic-orthodontic approach using a clinical case.
– Discuss briefly recurrence rate and psychological effects of condition.

Periodontal treatments involving cause-related therapy, resective and regenerative periodontal surgeries have been well documented over the last 30 years. In the era of esthetics, clinicians are seeking for optimal results by avoiding invasive treatments. Recent developments in regenerative techniques and adoption of microsurgery in periodontal and peri-implant tissue reconstruction minimize the tissue trauma/loss, and this led to an increase in the expectations of the patients. However, the clinical excellence does not only depend on the clinical skills or practice settings.

Treatment outcome is influenced by combination of many factors. For clinical success, treatment steps and protocols should be embraced by patient and clinician. In this lecture, the requirements for periodontal/peri-implant tissue reconstruction and health will be discussed in greater details.

Periodontal surgeries aim to restore and maintain the health and aesthetics of the periodontium. Among the critical aspects of successful periodontal surgery is the preservation of the interdental papilla. The contour of the interdental tissues, as well as the color and texture of the keratinized tissues, are essential elements of anterior esthetics. Preservation techniques, such as careful flap design, minimally invasive approaches, and meticulous handling of soft tissues are essential to minimize trauma and maintain blood supply to the papilla.

This presentation aims to highlight the significance of papilla preservation in periodontal surgery, the techniques, and their impact on the overall success of the procedure. Furthermore, the impact of patient-specific factors and anatomical considerations on papilla preservation outcomes is also addressed. By prioritizing papilla preservation and employing evidence-based techniques, periodontists can enhance treatment outcomes and patient satisfaction in periodontal surgery.

Objectives:
– To understand papilla preservation flap surgical technique.
– To learn how to maintain papilla form.
– To learn how to preserve soft tissue in esthetic areas.

Smile aesthetics are closely related to smile lines and smile arcs. Gummy smile, where more than 2 mm of gums are exposed when smiling, is an aesthetic issue that many patients concerned about. Gummy smile are associated with delay passive eruption and are successfully resolved with crown lengthening solution.

However, crown lengthening is not the only solution to treat a gummy smile because gummy smile is caused many different etilologies that need many other solutions to treat it successfully. This presentaiotn analyzes the different causes of gummy smile and corresponding treatment solutions, in which many cases require integrated treatment through many illustrative clinical cases.

Periodontal disease is an inflammatory condition of the periodontium characterized by attachment loss, and ultimately, tooth loss. Tooth loss is the initiating event of masticatory dysfunction, which may only be noticeable to the patient once a substantial amount has occurred. A significant concern that comes with this dysfunction is the difficulty in its diagnosis, and the limitations it poses on restoration and rehabilitation. The presence of masticatory dysfunction is the delineating factor between a diagnosis of Stage III and Stage IV Periodontitis.

However, being the ambiguous concept that it is, it creates gray areas in both diagnosis and treatment, and subsequently, implementation in the clinical practice that present research continuously aims to decode. Recently, a guideline on the diagnosis and management of these cases has been published demonstrating current evidence which includes clinical investigations that may make it more applicable to the daily practice.

Objectives:
– To give a brief revision on the current classification of periodontitis.
– To discuss the criteria that are unique to the Stage IV classification
– To present the proposed framework on treatment sequence for management of Stage IV cases.
– To emphasize the key concepts in setting treatment goals and management of Stage IV cases.
– To introduce current evidence on the clinical application for the diagnosis of masticatory dysfunction.

The clinical judgment of whether to retain periodontally compromised molar through comprehensive periodontal therapy or to extract and replace them with dental implants involves a multifaceted decision-making process that extends beyond the scientifically reported efficacy of the two treatment modalities. This decision has to factor in multi-level elements, including but not exhaustive of the subject, dentition, and site-associated risk factors; periodontal, restorative, endodontic, and occlusal considerations; the strategic value of tooth in dentition; patient’s economics and predilection; and the clinician’s skill and level of training.

This presentation will evaluate the existing modern approaches, efficacy, and cost efficiency related to treatment and maintenance of periodontally compromised molars. Furthermore, we will delve into the biological ramifications stemming from the ultimate loss of these molars and examine the strategies and implications associated with rehabilitating these residual ridges with dental implants. The significance of considering both patient and site-level factors when planning tooth extraction and formulating implant rehabilitation protocols will be highlighted.

Objectives:
– Appraise the current evidence in the contemporary strategies, predictability, and cost effectiveness in the retention of periodontally compromised molars in the life course of periodontal patients.
– Predict alveolar healing patterns and sinus pneumatization following loss of periodontally compromised molars and comprehend the challenges associated with implant rehabilitation.
– Discuss the efficacy of alveolar ridge preservation in periodontally compromised molar extraction sites.

There are several advantages of using an allogenic bone block for vertical bone regeneration. Firstly, very good stability can be obtained at the surgical site after fixation of the block. Secondly, there is no donor site morbidity which is a complication when harvesting autogenous block bones. Thirdly, there is no need for the fixation of the barrier membrane for stability which can be a technically demanding procedure. However, the number of studies on vertical bone augmentation using the allogenic bone block is low. In this presentation, clinical cases of vertical ridge augmentation using irradiated allogenic cortico-cancellous bone will be shown including radiographic and histological evidence.

Objectives:
– Clinical indications of vertical bone augmentation using the allogenic block bone.
– How to achieve appropriate fixation of the block bone.
– The appropriate combination of regenerative materials when using the block bone.
– The amount of vertical bone gain that can be expected using the allogenic bone block
– Histological appearance of the regenerated bone using the allogenic block bone.

Periodontitis is a multi-factorial chronic inflammatory condition which affects the supporting tissues of the tooth. Periodontal disease and diabetes have bi-directional relationship. The host response against periodontal pathogens results in release of various inflammatory mediators which may have profound effects on systemic condition notably Type 2 Diabetes Mellitus. Netrin-1 are the laminin-like secreted neuronal guidance protein which acts as a guidance cue in the developing central nervous system.

They function either chemo-attractive or chemo-repulsive through DCC and UNC-15 receptor respectively. MCP-1 has a significant role in the pathophysiology of several diseases as a critical modulator of monocyte chemotaxis and T-lymphocyte differentiation. This study was designed to evaluate the levels of Netrin-1 and MCP-1 in Gingival Crevicular Fluid (GCF) and serum in Stage III Grade B Periodontitis, T2DM and Obesity.

Objectives:
– To estimate the levels of Netrin-1 and MCP-1 in GCF and serum in periodontally healthy subjects, Stage III Grade B periodontitis subjects, with and without Type 2 Diabetes Mellitus and Obesity.
– To find out association between Netrin-1 and MCP-1 levels in GCF and serum in periodontally healthy subjects, Stage III Grade B periodontitis subjects, with and without Type 2 Diabetes Mellitus and Obesity.
– To compare and correlate between the levels of Netrin-1 and MCP-1 in GCF and serum in periodontally healthy subjects, Stage III Grade B periodontitis subjects, with and without Type 2 Diabetes Mellitus and Obesity.
– To explore the possibility of using Netrin-1 and MCP-1 as a marker of inflammation in Stage III Grade B periodontitis and relating with clinical parameters.

Recently, the development of injectable scaffolds for tissue engineering has been growing interest. To develop a novel scaffold for periodontal hard and soft tissue regeneration, bone graft pastes consisting of nano-hydroxyapatite, chitosan, and gelatin (nHA/KG) and also a crosslinked collagen/gelatin (Col/Gel) hydrogel has been designed. In vitro studies on physical, chemical, and biological characteristics were analyzed.

For nHA/KG paste, the viscosity characteristics resemble the gel phase. PO43-, CO32-, -OH, Amide I, and II functional groups were detected in nHA/KG paste. Increasing the collagen concentration in the hydrogel (Col-Gel) 1:2 showed the best degradability rate. 3D culture studies of MC3T3E-1 and MRC-5 on nHA/KG paste and HGFs on Col/Gel showed the percentage of cell viability >70%. Up-regulated expression of ALP, OCN, RUNX2, and COL1 were exhibited by nHA/KG pastes. Similar results were also found on COL1 expression by HGFs with Col-Gel. Both nHA/KG pastes and Col/Gel hydrogel are potentially injectable scaffolds for periodontal regenerative therapy.

Objectives:
To analyze the differences in the characteristics of nHA/KG bone graft paste and crosslinked collagen/gelatin hydrogel (Col-Gel) in periodontal tissue regeneration.

Life-long maintenance of natural teeth and prevention of premature tooth loss may in the long run, cost less for the patient in many aspects. For periodontally susceptible patients, this may not be an easy task as it requires a life-long commitment.

However, the good news is; periodontal therapy is highly predictable and well supported by scientific evidence. The lecture will explore the factors that influence the success of periodontal therapy, and the steps that can be taken to maintain teeth and implants in periodontally susceptible patients. Adjunctive use of local antibiotics for patients undergoing supportive periodontal therapy and the available evidence will also be examined.

The keratinized mucosa width (KMW) is an essential components of the peri-implant soft tissue phenotype. Less than 2 mm of KMW was found to be associated with local discomfort upon oral hygiene performance and increased risk for the onset of peri-implant diseases.

Several soft tissue augmentation procedures have been developed to increase peri-implant KMW and prevent biological complications around dental implants. Currently, the autogenous free gingival graft (FGG) is considered the clinical standard to gain KMW and thickness at implant sites, presenting favorable outcomes over time.

Theoretically, soft tissue augmentation could be performed at any time before/during/after implant treatment. It was once commented that the therapeutic approach to increase KMW was indicated and was most predictable before insertion of the dental implant.

The presentation aimed to discuss the effects and timing of autogenous soft tissue grafting for keratinized tissue augmentation at implant sites.

Predictable coverage of isolated and multiple mandibular gingival recessions is one of the most challenging endeavours in plastic-aesthetic periodontal surgery while the available data from the literature is still limited. In most of the described procedures, a split flap approach was adopted for preparing the flap, tunnel or envelope.

However, especially in the mandibular anterior area, a split flap approach may be difficult to perform and bears the risk of flap perforation and/or graft necrosis during the healing phase. In order to reduce these potential complications, modifications of the tunnel procedure, i.e. the Modified Coronally Advanced Tunnel (MCAT), the Laterally Closed Tunnel (LCT) or their combination have been introduced.

Learning outcomes:

1. To present the clinical indications for the treatment of single and multiple adjacent mandibulat gingival recessions.
2. To present the anatomical considerations and factors which influence the results.
3. To provide the biologic rationale, the step-by-step procedure and the results obtained with MCAT and LCT in isolated and multiple mandibular gingival recessions.

Dental implants having been applied to restore the lost dentition for more than fifty years, nevertheless, the time required from implant insertion to functional restoration still takes four to six months for osteointegration. Besides, once exposed to the oral environment, the poorly circulated bone surround implant is more prone to uncoupled bone loss and unresolved immune response induced by oral microbial challenge due to poorly vascularized peri-implant structure in comparison with periodontal structures generated from transplanted tooth.

Thus, how to rapidly replace missing teeth with bio-inductive dental implants remains a crucial and unresolved issue. Recent study found the topological signals may induce epigenetic changes in the attached stromal cells, lead to remodeling of the chromatin and activate genes that favor osteogenic differentiation. Our findings further demonstrate that laser-modified titanium surface not only provides topological cues for osteogenesis on gingival stromal cells but also enhance exosome production to promote coupled angiogenesis.

Objectives:
Laser-modified titanium surface provides topological cues for gingival stromal cells which promotes osteogenesis and coupled angiogenesis.

P4 Medicine is based on a proactive approach for clinical patient care incorporating the four “pillars” of prediction, prevention, personalization and participation for patient management. This lecture explores how the concepts of P4 medicine can be incorporated into the management of periodontal diseases. The proposed model of P4 Periodontics is highly aligned with the 2018 Classification of Periodontal Diseases and represents a logical extension of this classification into treatment paradigms. Each stage of periodontitis can be related to a holistic approach to clinical management.

The role of “big data” in future P4 Periodontics is discussed and the concepts of a treat-to- target focus for treatment outcomes is proposed as part of personalized periodontics. Personalized periodontal therapies will refocus our thinking from risk management to regenerative solutions to manage the effects of disease and aging.

Objectives:
– Understand the 4 pillars of P4 Medicine.
– Recognize how P4 Medicine concepts align with the 2018 Classification of Periodontal Diseases.
– Appreciate how P4 medicine concepts can be incorporated into periodontal disease management.

Supracrestal connective tissue attachment (SCTA), previously known as “biologic width,” is vital to the gingiva near the periodontal ligament (PDL). Recent research shows that violating the SCTA causes inflammation, loss of periodontal support tissues, and an apical shift of the junctional epithelium.

The supracrestal gingival connective tissue fibers, located near the gingival sulcus, are exposed to diverse microorganisms in dental plaque biofilms. This proximity suggests that supracrestal gingival connective tissue-derived mesenchymal stem cells (SG-MSCs) might help maintain tissue homeostasis. SG-MSCs have emerged as promising for periodontal tissue regeneration. They showed the highest cell proliferation rates among marginal gingival tissue-derived MSCs (MG-MSCs) and PDL-MSCs, with similar gene expression profiles to PDL-MSCs.

Although SG-MSCs have slightly lower osteogenic differentiation potential than PDL-MSCs, their accessibility and resource availability make them good candidates for periodontal regeneration. Understanding SG-MSCs’ molecular properties is crucial for their therapeutic use in periodontal tissue regeneration and homeostasis.

Accumulation of supra- and sub-gingival dental biofilm around implant restorations often lead to peri-implant tissue inflammation. Compared to a periodontitis lesion, a peri-implantitis lesion is characterized by a greater area of infiltrated connective tissue and a non-linear accelerated bone loss pattern.

Therefore, early detection and intervention are crucial for effective management and prevention of disease progression. Several treatment modalities, that can be broadly categorised into non-surgical and surgicalmethods, have been used to manage this inflammation.

This presentation aims to provide an overview of the nature of peri-implant tissue inflammation, discuss the various treatment modalities and outline the desired treatment endpoints for optimal clinical outcomes.

The decisive role of soft tissue in the success of periodontal and implant treatments, both functionally and aesthetically, has been proven. Dentistry today aims to preserve or regenerate soft tissue around teeth and implants of optimal volume, quality and aesthetics. Soft tissue graft surgery is therefore increasingly widely applied in practice.

Until now, autologous connective tissue is still considered the gold standard in soft tissue graft surgery. Connective tissue grafting is gradually becoming a routine technique in periodontal and implant surgery. However, connective tissue grafting is a relatively complex, delicate and invasive surgery, requiring surgeons to be equipped with a solid knowledge base combined with proficient skills to achieve optimat and effective treatment results.

The presentation will cover the following contents:

• Indications for connective tissue grafting in periodontal and implant treatment
• Classify and select connective tissue grafts according to location, size and biological characteristics
• Classify and choose connective tissue grafting techniques based on the type of treatment
• Healing process after connective tissue graft surgery and factors determining success

Loss of hard tissue and soft tissue are unavoidable consequences after teeth missing. Hard tissue restoration is always considered as a challenge for implant surgeons. Meanwhile, soft tissue reconstruction is a more difficult problem to predict than hard tissue because the soft tissue structure around the implant restoration is often looser than the real teeth, so it is susceptible to soft tissue recession and loss of aesthetics as well as the high risk of peri-implantitis.

Consequently, this paper outlines preventive strategies and management techniques for soft tissue complications, derived from a 25-year experience in implant practice, along with clinical cases in soft tissue restoration around implants to ensure long-term functional and aesthetic success.

Key word: soft tissue augmentation, peri-implantitis
