Hypodontia Study Day 2017



The Kings Hypodontia study day is being held on the 19th of April at Kings College Hospital. This course is aimed at trainees and specialty grades but is likely to provide some useful information to consultants involved in the management of the condition that may be looking at updating the evidence base for decision making. 

Important issues such as definitions and aetiology and the need for joint planning will be presented followed by management of the mixed dentition and orthodontic considerations. Towards the end of the day techniques in adhesive dentistry such as the utilisation of composite and resin bonded bridges will be described. The last presentation will review the need for implants and considerations when providing these. 

Information on registering and attendance will be provided on the below link.

Do implants provide the best aesthetic outcome for patients with hypodontia ?


A study by Hvaring and colleagues has looked at the outcomes for patients with hypodontia and more specifically the treatment for missing teeth. They looked at a cohort of 50 patients with 6 missing teeth or more with a mean age of 26. These patients were examined clinically assessing mucosal discolouration, crown morphology, colour, and papilla index. 

Deciduous teeth showed good outcomes whereas implants had poorer results. Changes in gingiva colour was seen only for implants and occurred for all fixtures in the anterior mandible and the majority of those in the anterior maxilla. As you would expect papilla index scores were poorer for implants and conventional bridges when compared with orthodontic space closure.

Implants are a popular treatment modality in the management of patients with hypodontia as they provide tooth replacement without the need for adjacent tooth support or retention. Over time those working in the hospital services have seen case from 5 years or more return with either mechanical or biological complications. Patients with hypodontia may have adequate bone stock around the top of the ridge but this becomes more compromised higher in the alveolus. Over time the alveolus is likely to continue to resorb as illustrated in the above research resulting in mucosal discolouration due to the slow exposure implant threads. In such patients, who have such underdeveloped ridges, alternative tried and tested treatments maybe wiser to consider. Resin bonded bridges are predictable, efficient with good long term outcome data. Consideration for the patients long term maintenance-especially if treated in late adolescents-needs to be a significant consideration.

New evidence shows patients prefer closing spaces versus opening spaces when teeth are missing




Qadri and colleagues have surveyed lay members of the public to try and measure their perception of different types of orthodontic treatment and subsequent restorative treatment. Opening of lateral incisor spaces can be difficult to get right especially if there are other complicating factors. The closure of spaces obviously has its advantages. It removes the need for ongoing maintenance of a restoration such as a resin bonded bridge, this can be even more complicated and involved where implant restorations are planned in these sites which will potentially need grafting and long life maintenance...lets not mention the potential for complications ! 

Other issues to consider with space closure include the gingival profile of the canine, the depth of colour of the canine and its size and ability to be disguised with bleaching and bonding as a lateral incisor. In this research from a group in Sheffield (UK) they found that patients and laypeople preferred space closure from an aesthetic sense as opposed to having a restoration in the lateral incisor position.

Kings College Hospital Hypodontia Study Day on 4th of May 2016



The annual Kings College Hospital Study Day will take place on the 4th of May 2016 at the Weston Education Centre, Denmark Hill. The program will be delivered by staff of Kings who are directly involved in management of both adolescent and adult patients on a number of multidisciplinary clinics. Subject covered will include management of the developing dentition, orthodontic considerations, the provision of adhesive dentistry such as composite masking and resin bonded bridges in addition to the placement of implants.

Hypodontia is ideally treated in a multidisciplinary setting- A case report

The purpose of this article is to describe a team approach to treatment of hypodontia in adolescent dentition. A case report of hypodontia with a microdontic lateral incisor in a Class I malocclusion illustrates the principles of case management. Multidisciplinary consultation during treatment planning and coordination and appropriate timing of subsequent interdisciplinary dental care enables the clinician to provide the optimum care. The scope of orthodontic and restorative management depends on the severity of the hypodontia.
