Factores de risco em implantologia

Abstract

Dental implant teraphy has become very popular because of it’s predictable results in the reabilitation of edentulous sites, allowing the reduction of phonetic, aesthetic and functional consequences that come with tooth loss, and it does so by using a fixed and well-accepted solution. However, implant therapy must be carefully weighted as each pacient is unique. This is a literature review about risk factors, failures and complications inherent to implant therapy. The risk factors were organized according to it’s relationship with the surgeon’s experience, thecnique and surgical procedure; the patient; local factors such as bone and soft tissue quantity and quality; factors regarding the implant itself (dimentions, surface treatment and design); factors related to the prosthetic phase, such as type of prothesis and loading; and peri-implant deseases such as mucositis and peri-implantitis. A research was done using the online database MEDLINE/PubMed on the key-words “implantology risk factors”, “complications in implantology”, “implantology failures”, then the articles and publications found were used according to it’s relevance to the present work. Whilst the success rates of implant therapy are high, there are still failures. There are no absolute contraindications to implant therapy, nevertheless some conditions are considered a major risk. The challenge in implantsuported- rehabilitations relies on the physician's ability to evaluate and classify the constraints of each patient, and deliver a treatment plan according to these multifactorial limitations.
