Digital Planning and Clinical Assessment of the Treated Atrophic Posterior Maxilla With a Sinus Lift Procedure: a Cross-sectional Study.

Recruiting now

Conditions studied: Alveolar Bone Atrophy, Alveolar Bone Grafting, Peri-Implant Health, Sinus Floor Augmentation, Vertical Ridge Deficiency, Guided Bone Regeneration, Digital Guided Bone Regeneration, Prosthetic Complication

In brief

Maxillary posterior area is the most challenging site for dental implant placement. Indeed, complex remodeling processes, resulting in changes of the maxillary sinus and shape of the alveolar ridge will cause difficulties in rehabilitating the posterior maxillae sites. Various techniques have been proposed in order to achieve the necessary bone volume for the placement of long term successful implants. However, unbalanced crown to implant ratio remains a risk factor after successful dental implants installation following sinus graft. No study on humans assessed the effect of apical positioning of the implants in posterior grafted sites (sinus graft or sinus graft + vertical GBR) on the following clinical parameters: The peri-implant bone remodeling (vertical bone loss (mm) and probing depth (mm) around the implants, crown bulkiness, emergence profile and crown height, and Patients satisfaction, food impaction (PROM)). This study will elucidate these points and based on the parameter's results, suggest a treatment based classification facilitating the treatment decision-making of the clinicians in case of an atrophic posterior maxilla; aiming to ensure a long-term successful supra-implant rehabilitation which will maintain its bio-mechanically and biological success.
