A Review of Dental Implant Treatment Planning and Implant Design Based on Bone Density

Abstract

Context:A key determinant for clinical success is the diagnosis of the bone density in a potential implant site. The percentage of boneimplant contact is related to bone density, and the axial stress contours around an implant are affected by the density of bone. Evidence Acquisition: A number of reports have emphasized the importance of the quality of bone on the survival of dental implants. The volume and density of the recipient bone have also been shown to be determining criteria to establish proper treatment plans with adequate number of implants and sufficient surface area. Previous clinical reports that did not alter the protocol of treatment related to bone density had variable survival rates. To the contrary, altering the treatment plan to compensate for soft bone types has provided similar survival rates in all bone densities. Results: When bone density decreases and bone become softer, the implant surface in contact with the bone decreases, therefore treatment plan should be modified by changing the drilling protocol, using gradual loading and reducing the force on the prosthesis or increasing the loading area with increasing implant number, implant position, implant size, implant design (deeper and more threads with more pitch, squared shape) and implant body surface condition. Conclusions: Once the prosthetic option, key implant position, and patient force factors have been determined, the bone density in the implant sites should be evaluated to modify the treatment plan. Inappropriate implant number or design in poor quality bone results in higher failure rates. Changing the treatment plan and implant design is suggested, based on bone density to achieve higher survival rates.Keywords:Bone Density; Dental Implant; Implant Design Implication for health policy/practice/research/medical education: Providing the long-term survival rate and higher success rate of dental implant in poor bone quality/Ideal treatment planning based on making proper decisions; make a selection based on a scientific approach, rather than on advertising or marketing opinion.

Evidência Científica Para Uso Do Fio Dental No Controle De Biofilme E Inflamação Gengival

“…Com o objetivo de avaliar o momento ideal de uso do fio dental, se antes ou depois da escovação, Torkzaban et al 18 (2015) realizaram um ensaio clínico com 35 estudantes de Odontologia. Os sujeitos foram convidados a usar fio dental e depois escovar os dentes por um período de 2 semanas (FB), seguido de escovação mais uso do fio dental por outro período de 2 semanas (BF).…”

Efficiency of orthopantomogram and cone beam computed tomography when planning implants in anterior mandible.

“…Кey positions for the placement of implants, are the end retainers for the prosthetic suprastructure, and the jaw regions with reduced biomechanical forces that are damaging for the implant and the surrounding bone 7 . When planning implants in edentulous regions, the height of the residual alveolar ridge, determined through radiographic methods, presents the distance from the crestal part of the alveolar ridge to the neighbouring anatomical structure,while the width of the residual alveolar process presents the distance from the buccal side of the alveolar ridge to the lingual side of alveolar ridge 8 . Radiographic evaluation in the regions planned for implant placement, plays a crucial role in identification and analysis of anatomical-sceletal relationship of important neighbouring anatomical structures.…”
