Full Mouth Rehabilitation of a Rare Case of Hypodontia: A Case Report

TL;DR

This case report describes the dental rehabilitation of a young man with a rare form of hypodontia involving 21 missing teeth.

Contribution

The paper presents a detailed multidisciplinary treatment workflow for a rare hypodontia case involving full mouth rehabilitation.

Findings

A step-by-step approach from diagnosis to full mouth rehabilitation was successfully implemented.

Implant-supported and tooth-supported ceramic restorations improved esthetics and function.

A multidisciplinary approach and predefined workflow led to satisfactory and predictable outcomes.

Abstract

Hypodontia with one or two permanent teeth is a common anomaly in dental clinics, while missing more than six is rare. Management of these cases is challenging because, other than the missing tooth problem, bone formation deficiency, imperfect vertical dimension of occlusion, and available tooth displacement will complicate the treatment procedure. Being in early youth and having high esthetic demands make these patients even more difficult to treat. Before starting the treatment, an exact diagnostic procedure is essential to pick the best treatment option. Also, to achieve predictable and satisfactory results, a predefined workflow is useful. The current study presents a step-by-step procedure from diagnosis to full mouth rehabilitation of an 18-year-old man who suffered from hypodontia with 21 missing permanent teeth. A diagnostic work-up was carried out and mocked up in the mouth. Dental implants were inserted, and printed provisional restorations were evaluated in terms of esthetics, phonetics, and vertical dimension. Implant-supported and tooth-supported full ceramic restorations were made based on the treatment plan. Mutually protected occlusion was designed and implemented. At the end, an occlusal splint was made to care for the restorations. The main take-away lesson from this case is that in the treatment of hypodontia patients, all treatment options should be evaluated, and a multidisciplinary approach should be followed.
