Esthetic and Colorimetric Assessment of Peri-implant Soft Tissue Augmented with the Strip Gingival Graft Harvested Either from the Buccal Soft Tissue or the Palate: A Retrospective Study.

It is well known that keratinized mucosa (KM) plays a crucial role for maintaining peri implant health and esthetic outcomes. The Strip Gingival Graft (SGG) technique, which involved an apically positioned flap (APF), in combination with an autogenous SGG and a xenogeneic collagen matrix (XCM), demonstrated its efficacy in re-establishing an adequate amount of KM width at implant sites. Nevertheless, it is still unclear whether harvesting the SGG from the palate (pSGG) or from the buccal aspect of natural dentition (bSGG) affects the esthetic outcomes at the augmented implant sites.

The Impact of Membrane Stabilization for Alveolar Ridge Preservation in Periodontally Compromised Extraction Sockets: A Non-Inferiority Randomized Controlled Trial.

Aim: The aim of this study was to investigate the non-inferiority of alveolar ridge preservation (ARP) with membrane stabilization compared with non-stabilization, focusing on changes of soft-tissue contour in periodontally compromised extraction sockets. Secondary outcomes included changes in hard-tissue contour, patient-reported outcomes and new bone formation.

Materials And Methods: Twenty-four patients with periodontally compromised teeth were randomly assigned to ARP with (test group) or without (control group) membrane stabilization.

Regeneration of Chronic Alveolar Vertical Defects Using a Micro Dosage of rhBMP-2. An Experimental In Vivo Study.

Objective: The objective of this study is to compare the effect of the location of recombinant human bone morphogenetic protein 2 (rhBMP-2) from the native bone and the periosteum for vertical alveolar bone augmentation.

Materials And Methods: Mandibular, chronic, standardized, bilateral, and vertical defects in 12 beagle dogs were evaluated using four modalities: a xenograft alone (XENO; n = 6); rhBMP-2 alone (BMP; n = 6); a technique with rhBMP-2 close to the host bone covered by xenograft (SAN; n = 6); and a technique with rhBMP-2 close to the flap on top of the xenograft (LAS; n = 6). After 8 weeks, a series of in vivo inspections, fluorescence microscopy, histologic and histomorphometric evaluations, and micro-CT analyses.

Submerged vertical bone augmentation of supraosseous peri-implant defects.

Case Presentation: Although most peri-implant lesions feature a combined defect configuration that involves both supra- and infraosseous components, regenerating the supraosseous part is considered the optimal approach, albeit a challenging one, and often requires vertical bone augmentation. This report provides a detailed description of submerged membrane techniques for vertical bone augmentation around supraosseous peri-implant defects. Cases involving different types of membrane (both resorbable and non-resorbable) with or without the use of bone graft are presented.

Simple-Challenging-Difficult (SCD) Difficulty Classification for Vertical Bone Augmentation.

Objective: To propose a new difficulty classification for vertical bone augmentation (VBA) based on different defect morphologies.

Overview: VBA procedures for dental implant placement present significant biological and technical challenges. Among the various techniques, guided bone regeneration (GBR) provides an optimal balance between the anticipated bone gain and the likelihood of postoperative complications.
