IMPLANT THERAPY OF HYPODONTIA - SURGICAL ASPECTS
Professor Dr Aleksa Marković
Clinic for Oral Surgery, School of Dental Medicine, Belgrade University

Hypodontia, or tooth agenesis, has multifactorial aetiology that
includes genetic regulation and environmental factors. The prevalence of hypodontia in permanent dentition ranges from 1.6% to 36.5%, depending on the population tested, and usually involves mandibular second premolars unilaterally or maxillary lateral incisors bilaterally.

Considering clinical characteristics of the hypodontia, implant therapy in these patients requires a multidisciplinary approach to ensure aesthetically and functionally successful outcome. A sufficient space for implant placement is often necessary to provide by applying orthodontic therapy. Patients with congenitally missing teeth may present with undeveloped alveolar bone morphology, and ridge augmentation might be required in order to provide bone volume for adequate prosthetically driven implant positioning. Careful selection of dimensions and macro design of implants is important for the aesthetic success of the treatment, since they are performed mainly in the aesthetic zone. Implant treatment significantly improves oral health related quality of life in young patients with hypodontia. Clinicians should choose the appropriate time for implant treatment , understanding the risk associated with infraocclusion whan placing implants who heal ankylotic in jaws that are still growing and developing.

In this lecture, timing and surgical protocol for implant treatment in patients with hypodontia will be discussed.
