The reconstruction of the atrophic alveolar ridges for implant placement is today a common procedure in dentistry daily practice. The surgical reconstruction provides for the optimization of the supporting bone for the implants and a restoration of the amount of keratinized gingiva for esthetic and functional reasons. In the past, tissue regeneration has been performed with autogenous bone and free gingival or connective tissue grafts. Nowadays, bone substitutes and specific collagen matrix allow for a complete restoration of the atrophic ridge without invasive harvesting procedures. A maxillary reconstruction of an atrophic ridge by means of tissue substitutes and its histological features are then presented.

Autologous Bone

Introduction:Autologous bone is considered to be the “gold standard” for the reconstruction of the reabsorbed alveolar ridges. For small defects, autologous bone samples can be harvested from intraoral donor sites. However, extraoral donor sites are the first choice for any extensive augmentation of the alveolar ridges. The resorption of the bone grafts depends on several factors, including the recipient sites, the donor sites, volume of the bone grafts and whether or not the patient smokes. The aim of this study was to investigate the rate of autologous bone graft resorption, 4 months after the surgical reconstruction, according to their sites of origin, parietal or ramus, according to the grafted site, mandible or maxilla and according to the surgical indications.Patients and methods:22 patients had 51 reconstructions of alveolar ridges with ramic or parietal onlay bone grafts. The increase of bone volume was assessed with computed tomography, immediately after augmentation (V0) and 4 months after the procedure (V1), before the placement of dental implants.Results:The mean rate of bone resorption was 26% for the parietal bone grafts and 27% for the ramus bone grafts after 4 months (p: ns). This rate was 26% for maxillary grafts and 25% for mandibular grafts (p: ns). This rate varies from 22% to 33% according to the etiology of the bone defect but these variations are not significant and ultimately, this rate of bone resorption was unaffected by the gender of patients.Conclusion:Based on these findings, the resorption of onlay grafts doesnʼt seems to be affected by the recipient and donor sites nor by the etiology of the bone defects. Parietal and ramic bone grafts showed limited resorption rates for the pre-implant reconstruction of alveolar ridges.

Implant Placement

Several techniques have been proposed for bone regeneration in patients with atrophic ridges. Nowadays, GBR represents the gold standard, and it allows obtaining sufficient bone volumes for a correct implant-prosthetic rehabilitation. Our goal is to perform a systematic review of the literature on the use of titanium meshes in GBR in order to evaluate the reliability of the procedure, the regeneration obtained, and the failures. Furthermore, we will evaluate the success and survival rate of the inserted implants. The selected articles concern vertical and/or horizontal regeneration of the alveolar ridge using titanium grids, in association or not with biomaterials, before and simultaneously with implant placement. Six articles were selected for the present review, including a total of 139 patients, 156 sites, and 303 implants. Titanium grids in combination with autogenous bone were used in 2 cases, 5 in combination with a mixture of autogenous bone and bone substitutes. The overall survival and success rates of implants were 98.3% and 85.25%, respectively. In conclusion, our review shows how the use of titanium mesh represented a predictable method for the rehabilitation of complex atrophic sites.

The periodontal treatment of teeth with furcation defect is clinically challenging. In cases of class II furcation defects, the regenerative surgery shows low morbidity and good prognosis when correctly indicated. The aim of the presentstudy is to report a treatment option for class II furcation defect through autogenous bone graft associated with the Bichat’s fat pad. Case report: A 59-year-old female patient was diagnosed with class II furcation defect in the left mandibular first molar. The treatment comprised surgical reconstruction of the defect with a combination of maxillary tuberosity bone graft and Bichat’s fat pad. The clinical and radiographic follow-up of 180 days showed bone formation inthe furcation area and absence of probing depth. Conclusion: An association of autogenous graft form the maxillary tuberosity with a Bichat’s fat pad proved to be a safe, low cost, and effective therapy for the regenerative treatment of class II furcation.

Implants and biomaterials used in hard and soft oral tissue augmentation are very complex, but predictable to use nowadays, as the technological advances haven�t skipped this field of medicine. Cases that were impossible to treat with implant retained fixed prosthesis some years ago, have become the daily practice of oral surgeons and dentists around the world. The new user-friendly products, together with simplified protocols, increased the practitioners� predictability and success rate, thus the biomaterial industry took a huge leap forward. As the biomaterial industry keeps developing continuously, making better and safer products, the surgical and prosthetic protocols evolve and change as well. On this matter, the implant placement has become safer, using digital surgical guides. Guided implant placement doesn�t just allow the practitioner place the implant in the patient�s bone, but, moreover, it helps him place it in the correct, 3D, prosthetic position. And, thus, guiding the future bone augmentation and regeneration as well, accordingly. So, the implant placement has shifted from bone-orientated to prosthetic-orientated, offering at the same time a better primary stability for the implants, due to the prior planning. The present clinical study aims to analyze the outcome of the digital guided protocol. Unlike the free-handed surgery, the digital guided surgery allows dentists and oral surgeons to place implants according to the future prosthetic position of the crowns, even in conditions of alveolar ridges with bone resorption. Moreover, it makes possible the �one day implant� concept, the dental technician being able to create the provisional crown/s in advance, knowing precisely the future position of the implant placement. So, at the time of the surgery, the provisional crown is also put in place, guiding the soft and hard tissue healing and also giving the patient a greater satisfaction.

Atrophic Maxilla

The guided bone regeneration (GBR) technique has been used to achieve optimal bone volume augmentation and allow dental implant placement in atrophic maxilla and mandible, with predictable results and high survival rates. The use of bone substitutes has reduced the necessity of autogenous bone grafts, reducing the morbidity at the donor areas and thus improving the patients’ satisfaction and comfort. This clinical case report shows a clinical and histological evaluation of the bone tissue behavior, in a case that required the horizontal augmentation of the alveolar ridge, with the use of xenograft biomaterial and further dental implant placement. After six months of healing time, six implants were placed, and a bone biopsy was done. The histological analysis depicted some fragments of the xenograft bone graft, integrated with the new-formed bone tissue.
