Types and tissue sources of bone grafts in dental implants

Using bone grafts has been described in the literature for multiple decades and has been applied within the different medical fields. Furthermore, in the field of dentistry, evidence shows that these approaches have been widely used for different purposes, including the management of craniofacial defects and dental implantology. However, it should be noted that many disadvantages have been reported for the different tissue sources of bone grafting in dental implants despite the wide acceptance of the outcomes and favorable prognosis with these materials. Therefore, many efforts were conducted to innovate further approaches with reduced disadvantages and favorable outcomes. Our present study discusses the types and tissue sources of bone grafts in the settings of dental implants. This can provide dentists with better information and enhanced knowledge levels about the tissue sources of dental implants, which should help them decide the most appropriate source with the least adverse events. Different tissue sources were reported in the literature, including materials that are no longer used for their disadvantages and associated complications. Among the proposed materials, biomimetics has been reported with favorable outcomes and reduced adverse events, and using combinations of these materials can furtherly enhance the prognosis. Further research is needed to innovate additional modalities that can overcome the currently reported limitations.

Introduction: When a dental element is lost in the posterior region of the maxilla, there is natural reabsorption of the alveolar process and at the same time there will be pneumatization of the maxillary sinus. It will increase its volume towards the place where the roots existed and this will often make it difficult or impossible to restore implants in place. For this reason, the procedure for elevating the floor of the maxillary sinus or short implants should be performed when possible. In this context, allogeneic, xenogenous, and alloplastic bone grafts are an alternative for the treatment of bone defects in the jaws, since they avoid the need for a second surgical access. However, due to the need for processing to eliminate antigenic components, these grafts are only osteoconductive with a lower bone formation potential compared to autogenous bone grafts. Also, in this context, in the last 20 years, platelet concentrates have been proposed as regenerative materials in tissue regeneration procedures. Among the platelet concentrates proposed in the literature, PRP and FRP are found to act as autogenous platelet aggregates with osteoinductive properties. Objective: The present study aimed to conduct a wide literature review on maxillary sinus surgery using fibrin-rich plasma. Methods: Experimental and clinical studies (case reports, retrospective, prospective and randomized) with qualitative and/or quantitative analysis were included. Results: The total of 48 articles were found involving Maxillary sinus surgery, Fibrin-rich plasma, and Biomaterials, of which 22 were selected to compose the present study. Conclusion: Based on the literary findings, it was shown that the FRP is favorable for bone formation processes for dental implants, especially when combined with xenografts.

Introduction of dental implants and more concern in patients about esthetics after loss of natural teeth increases the demand of bone grafts. Various types of bone grafts as allografts, xenografts and autografts are used all with their own pros and cons. Bone grafts are more likely to succeed when the conditions at the recipient site are favourable and certain requirements are fulfilled. This review explores the use of various bone grafts in implant dentistry.

Alveolar Bone Grafting

Objective To evaluate changes in the optical density of secondary alveolar cleft bone grafts obtained from two different donor sites over time and to determine whether one donor site gives a higher recipient bone density than the other. Methods A prospective study was performed evaluating 40 healthy patients with congenital cleft lip and palate undergoing secondary alveolar bone grafting, 20 (14 boys and 6 girls) having iliac crest and 20 (12 boys and 8 girls) receiving tibial bone grafts. Bone harvest and grafting was carried out by one operator (G.P.). Optical density of iliac and tibial grafts measured using a computerized densitometer, was compared at 6 days, 6 weeks, and 3 months. Due to interference from orthodontic appliances, optical density measurements for 16 subjects were not possible, and these patients were excluded from the study. The length of hospital stay postoperatively for both grafting procedures were recorded. Results A significant decrease in relative bone density was demonstrated during the 3-month postoperative period in both iliac and tibial bone graft groups (p < .05). The difference in densities between iliac crest and tibial groups were not significantly different at any of the time points (paired t test, p > .05). Subjects undergoing iliac crest grafts stayed an average of 5 days in the hospital postoperatively, compared with subjects with tibial grafts who stayed an average of 3 days postoperatively. Conclusion Optical density measurements of bone grafted into alveolar clefts, reported here for the first time, provide a valuable objective assessment of graft progress. Tibial and iliac crest grafts gave similar optical densities at recipient sites over the first 3 months. Iliac crest grafts required significantly longer postoperative stay; an important consideration in selecting donor sites for secondary bone grafting.

Abstract The bone configuration surrounding anterior dental implants was postoperatively assessed using cone-beam computed tomography (CBCT). In 21 patients with a mean age of 41.5 years, 36 implants placed in the incisor region were postoperatively evaluated using CBCT. The rate of bone-to-implant contact (%) was calculated. The mean rate of bone-to-implant contact on the labial side was 78.3% with and 65.3% without bone grafts. The postoperative findings of incisor implants could be assessed using CBCT.
