Use and outcome of treatment with dental implants in children up to the age of 16 years in Sweden with special reference to hypohidrotic ectodermal dysplasia

Bergendal B*, Ekman A,  Nilsson P


The aims of the study were to investigate the use of dental implants in children up to the age of 16 years and to evaluate the outcome of treatment in terms of lost implants. Special attention was given to children with hypohidrotic ectodermal dysplasia, HED, and anodontia in the lower jaw, a situation where early implant treatment has been advocated in single case reports and statements from consensus conference.


A questionnaire was mailed to specialist clinics in oral- and maxillofacial surgery and prosthetic dentistry in Sweden, asking them to report age, gender, diagnosis and implants placed in children. After compilation of the answers, the teams who had treated children with HED were asked to send radiographs and clinical photographs. The documentation was distributed to three specialists in oral- and maxillofacial surgery who participated in a telephone conference on plausible reasons for implant loss.


Responses were obtained from 30 specialist centres. Six centres reported 26 treated patients, 18 girls and 8 boys, during a twenty year period, 1985-2005. The reasons for treatment were non-syndromic tooth agenesis (14), trauma (7), and HED (5). In all, 47 implants were placed and 11 were lost. In the HED group of five children with anodontia in the lower jaw, 9 out of 14 implants placed in the lower jaw were lost before loading. At the conference with oral surgeons about the high failure rate in children with HED, the small dimensions of the jaws, and peroperative conditions rather than HED per se, were thought to account for the loss of implants.


Dental implants is a rare treatment modality in young children in Sweden. In patients with HED and anodontia of the lower jaw 9 of 14 implants were lost before loading. Implant surgery in small children with HED must not be considered routine treatment and should ideally be centralized. Monitoring of ooutcomes through quality registers is advocated in HED and other rare disorders.
