Assessment of Labial Plate Thickness After Immediate Implant Placement Using Two Different Xenografts in the Esthetic Zone

This randomized clinical trial aims to evaluate labial bone plate changes following immediate implant placement in Type II extraction sockets using two different xenograft materials and de-epithelialized free gingival graft in the esthetic zone . Patients requiring extraction and immediate implant placement will be randomly allocated into two groups according to the xenograft material used for defect grafting. Clinical and radiographic outcomes will be assessed to determine dimensional bone changes and implant success

Alveolar Ridge Preservation Following Tooth Extraction.

Bone resorption after a tooth extraction is a generally accepted knowledge and has been demonstrated by many animal and human studies. Especially during the first three months followed by the tooth extraction, the volume of bone may change significantly without any interference. Thus, doing a ridge preservation procedure following the extraction is a common standard of care method to maintain the socket volume if implant placement is considered as a treatment option in the future. A variety of materials and methods have been used for ridge preservation. However, it's still inconclusive to determine the best material to maintain the ridge dimension, especially for membrane placement that allows for space maintenance to protect the grafting material. Furthermore, there is no evidence to show any treatment rationale is superior to any other ridge preservation method. In general, the membrane serves the function of the barrier and space protector. The periodontal surgeon use membranes to exclude the epithelium growth and to limit the collapse of the soft tissue into the healing alveolar socket. Regarding resorbable and non-resorbable membrane materials, both serve the function of protecting the graft material from the oral cavity. However, there are also many demonstrating that without membranes the extraction socket healed nicely without any interferences. The question to us is: Do we need the membrane to exclude the epithelium or any kind of surgical dressing material is sufficient enough to preserve the volume of the extracted ridge? The object of this study is to compare five popular membranes on the market that present different characteristics of the membranes.

Comparison of Piezoelectric and Conventional Surgery for Germectomy of the Lower Third Molar

The main objective of the study is to compare the effects of the piezoelectric surgery and the traditional technique on soft tissue edema in patients undergoing bilateral germectomy of mandibular third molars

Adjunctive Use of Polynucleotide and Hyaluronic Acid-based Gel in Alveolar Preservation After Tooth Extraction

Alveolar ridge resorption after tooth extraction is a physiological process that continues throughout the patient's life due to the loss of the periodontal ligament and lack of mechanical stimulation. Alveolar ridge preservation (ARP) techniques aim to minimize dimensional changes in the ridge after tooth extraction. These techniques involve grafting the socket to fill the bed and/or sealing it with a biomaterial. Currently, there is a polynucleotide and hyaluronic acid-based gel (Regenfast®) on the market that has proven useful in treating residual periodontal defects. Hyaluronic acid-based gels also appear to enhance the regenerative potential of critical bone defects in both in-vitro studies on rats and clinical studies. Therefore, this study aims to evaluate the clinical and histological effects of polynucleotide and hyaluronic acid-based gel in alveolar preservation procedures.

"Pontic-shield" Technique in Alveolar Ridge Preservation

Alveolar bone resorption after dental extraction frequently leads to situations in which long-term function and esthetic success of rehabilitations with dental implants is a challenge. "Pontic-shield" has been described as an alternative technique to maintain alveolar ridge after tooth extraction. The aim of this study is to analyze the effectiveness of "Pontic-shield" technique in alveolar ridge preservation comparing to fresh socket and ridge preservation using deproteinized bovine bone and a porcine collagen membrane.

Management of the Fresh Extraction Socket in the Aesthetic Area

After atraumatic tooth extraction and the assessment of the feasibility of immediate implant placement, patients will be randomly assigned to one of three treatment concepts: 1. Immediate Implant Placement and Immediate Provisionalization 2. Alveolar Ridge Preservation. After 4 months of healing an implant will be placed with simultaneous GBR and/or Soft Tissue Augmentation procedures, if needed. 3. Spontaneous Healing of the socket. After 4 months of healing, an implant will be placedwith simultaneous GBR and/or Soft Tissue Augmentation procedures, if needed. In all groups, four months after implant placement, a prosthesis will be delivered. From this experimental period onward, patients will be scheduled for maintenance. Clinical, radiographic and volumetric assessment will be performed by clinicians not involved in the surgery and blind with respect to treatment assignment at 1, 3 and 5 years post loading.

Effect Alb-PRF & A-PRF in Alveolar Ridge Preservation in Diabetes Patients - A RCCT

This study aim to investigate the effect of albumin gel- and platelet- rich fibrin(Alb-PRF) combined with advanced platelet-rich fibrin (A-PRF) on alveolar ridge preservation by comparing alveolar ridge morphometric changes (hard and soft tissue), prospects and treatment complexity for placement of prosthetically guided dental implant, early oral wound healing outcomes evaluated by the Inflammatory Proliferative Remodeling Scale, and patient reported outcome measures, in Type I/II Diabetes Mellitus patient, versus spontaneous healing
