Abstract

Background: bone augmentation by means of manually shaped titanium mesh is an established procedure to regenerate atrophic alveolar ridges and recreate a proper contour of the peri-implant bone anatomy. Conversely, current literature on the use of preformed titanium meshes instead of traditional grids remains lacking. Therefore, the aim of the present prospective study was to evaluate the use of preformed titanium mesh to support bone regeneration simultaneously to implant placement at dehiscence-type defects from clinical, radiological, and patient-related outcomes. Methods: 8 implants showing buccal dehiscence defects were treated with preformed titanium mesh directly fixed to flat abutments screwed to the implant. Intrasurgical clinical measurements and radiographic evaluations by means of cone-beam computed tomography scans were performed to assess the horizontal bone gain after 8 months from the augmentation surgery. Biological and patient-centered outcomes were also evaluated.; Results: clinically, a mean horizontal bone gain of 4.95 ± 0.96 mm, and a mean horizontal thickness of the buccal plate of 3.25 ± 0.46 mm were found. A mean horizontal bone gain of 5.06 ± 0.88 mm associated with a mean horizontal thickness of the buccal plate of 3.45 ± 0.68 mm were observed radiographically. From a macroscopic aspect, the remodeled graft appeared well integrated with the host bone. Well vascularized newly formed bone-like tissue was observed in intimate contact with the implants. Conclusions: preformed titanium mesh may be effective in supporting simultaneous horizontal bone regeneration at dehiscence-type peri-implant defects. Titanium mesh exposure still remain an issue in this type of surgery.

Summary

Introduction

Dental implantology is a well-established therapeutic alternative to replace missing teeth in fully and partially edentulous patients, providing good survival rates in both pristine and augmented bone in the long term [1,2,3]. Several anatomical and technique-related variables are involved in the maintenance of successful biological, functional, and esthetic outcomes Notable among these is the horizontal ridge dimension, with particular emphasis on the peri-implant buccal bone thickness (BBT), which strongly. Materials 2020, 13, 2389 impacts the hard and soft tissue stability In this regard, it has been claimed recently that BBT >1.5 mm should be sought to minimize adverse horizontal and vertical alveolar bone remodeling and provide a protective mechanism against the progression of peri-implantitis [4]. It has been claimed recently that BBT >1.5 mm should be sought to minimize adverse horizontal and vertical alveolar bone remodeling and provide a protective mechanism against the progression of peri-implantitis [4] Such experimental findings corroborate available data from previous clinical investigations on the critical role of the BBT.
