Free gingival graft and acellular dermal matrix for gingival augmentation: a 15-year clinical study.

Objectives: This study evaluated clinical outcomes of acellular dermal matrix (ADM) allograft compared with autogenous free gingival graft (FGG) for gingival augmentation after 15 years.

Material And Methods: Twenty-two patients were originally included and evaluated by de Resende et al. (Clin Oral Investig 23:539-550, 2019), and 12 accepted to participate in this longitudinal evaluation.

Acellular dermal matrix allograft versus free gingival graft: a histological evaluation and split-mouth randomized clinical trial.

Objectives: This split-mouth controlled randomized clinical trial evaluated clinical and histological results of acellular dermal matrix allograft (ADM) compared to autogenous free gingival graft (FGG) for keratinized tissue augmentation.

Material And Methods: Twenty-five patients with the absence or deficiency of keratinized tissue (50 sites) were treated with FGG (control group) and ADM (test group). Clinical parameters included keratinized tissue width (KTW) (primary outcome), soft tissue thickness (TT), recession depth (RD), probing depth (PD), and clinical attachment level (CAL).

Bone Graft and Substitutes Associated with Titanium Dome for Vertical Bone Formation in Osseointegrated Implants: Histomorphometric Analysis in Dogs.

Purpose: This animal study investigated vertical bone formation (VBF) around implants and used histomorphometric analysis to compare different bone-filling materials associated with a massive titanium dome as a tissue barrier.

Materials And Methods: Seven dogs were submitted to surgical procedures with extraoral access to the lower edge of the mandible, and four implants were semi-inserted in each animal. Each implant received one treatment: autogenous bone with clot (AB), control clot (C), synthetic graft (Biogran [BG]), or xenograft (Bio-Oss [BO]).

Prosthetic rehabilitation of a bone defect with a teeth-implant supported, removable partial denture.

The use of teeth-implant, mucosa-supported removable dentures for rehabilitation of partially edentulous patients involves highly complex biomechanical aspects. This type of prosthesis associates 3 kinds of support that react differently to the functional and parafunctional forces developed in the oral cavity. Although the construction of removable partial dentures may seem paradoxical when osseointegrated implants are placed, in some cases, this option is an excellent alternative to solve difficulties related to the anatomic, biologic, psychomotor, and financial conditions of the patient.
