Alternative Gingival De-Epithelialization Techniques

The goal of this clinical trial is to compare different de-epithelialization methods in patients undergoing soft tissue augmentation surgery. The main questions it aims to answer are: • Which technique is superior for de-epithelialization in terms of remaining epithelium, wound healing of the donor site, and clinical outcomes?

Histological and Volumetric Evaluation of Customized Allograft Bone Blocks

Customized bone blocks need CBCT and digital software to design the block needed to rehabilitate. Some advantages are reduced surgical time and better adaptation of the graft, leading to less complications. Objectives: The primary aim of this study is to determine the bone regeneration capacity through a histological study and the bone volumetric changes of allograft bone blocks in the posterior site of the mandible. The secondary outcome will be to assess the survival and success rate of dental implants placed in the allograft regenerated area. Materials and Methods: After studying the CBCT to regenerate the posterior sites of the mandible, the investigators will design CAD/CAM freeze- dried bone allograft to fit exactly on the defect morphology that the patients present. A full thickness flap will be released to have a correct access of the defects. The sterile blocks have to fit perfectly on the defect and fixed by screws. Covered with resorbable membranes fixed with pines and suture. 4 months later, 2nd CBCTwill be performed. During the implant surgery, a bone trephine will be removed and sent into a Laboratory to make a histological study of the bone block for histomorphometry. After 3 months, second-stage surgery and healing caps will be placed if needed. Impressions will be taken 2 weeks after to perform the final crowns.
