Introduction: Implant-prosthodontic treatment for restoring a single missing tooth, partial edentulism and complete edentulism is a redictive and successful method in terms of both the survival rate of implants and the different parameters which determine the success rate of the treatment. The purpose of this study was to evaluate the 10-year survival and success rates of dental implants, analyze the causes of early and late complications, and assess the type and number of prosthodontic complications. Patients and methods: In 51 patients, 113 titanium dental implants were inserted by one surgeon using a two-stage surgical protocol. The prosthodontic treatment included fixed or removable treatment options. Implant survival and success were evaluated 10 years after the completion of prosthodontic treatment. The evaluation comprised history, clinical examination with assessment of success parameters (prosthesis functionality, peri-implant tissue status), and x-ray assessment of bone loss. Results: Two implants were lost before and two 10 years after the prosthodontic treatment. The survival rate of implants was 96.4 % on the average, 100 % in the lower jaw, and 92.5 % in the upper jaw. Peri-implantitis was diagnosed in 4.5 % of all implants. The success rate was thus 95.5 %. Technical complications occurred in 2.8 % of fixed prostheses and 19 % of removable prostheses. Conclusion: The long-term survival and success rates of dental implants are high. Proper implant prosthodontic treatment planning is crucial to achieving high survival and success rates of implant treatment. Bone quality has to be taken into account when implant treatment is performed. Peri-implantitis is rarely observed, and prosthodontic complications are uncommon. On completion of the surgical and prosthetic phases of treatment, patients must be followed at regular intervals to ensure timely management of complications.

Background: Ectodermal dysplasia (ED) is a group of hereditary diseases with disorders in the development of two or more ectodermal structures, such as hair, teeth, nails and sweat glands. The symptoms of craniofacial anomalies express themselves with a larger number of unerupted teeth - oligodontia. Facial characteristics appear because of disorders in the growth of facial bones due to congenitally missing teeth related to underdeveloped alveolar ridge. Treatment planning in these patients requires interdisciplinary approach, and should include various possibilities of substitution of congenitally absent teeth, orthodontic treatment, orthognatic surgery, skeletal augmentation, surgical insertion of dental implants, prosthetic rehabilitation and genetic counseling. Case presentation: In a patient with ectodermal dysplasia, clinical examination and analysis of panoramic x-ray revealed 17 congenitally absent permanent teeth with extensive atrophy of the alveolar ridge, hypotrichosis, narrow face, prominently expressed chin with speech and mastication difficulties. Rehabilitation planning included an extensive interdisciplinary approach with orthodontically guided three-dimensional correction of the upper and lower jaw relationship that was followed by a surgical open lift of the sinus floor on the right side and insertion of four dental implants. In the mandibular arch, the missing teeth were replaced with a metal-porcelain bridge on the supporting teeth and with two bridges supported on the dental implants in the maxillary arch. After 12 years of interdisciplinary treatment the patient was successfully rehabilitated. Conclusion: Treatment of patients with ectodermal dysplasia andoligodontia is individual and must be targeted mainly at prevention, for itis necessary to conserve the patientʼs own teeth and at the same time replace (the) missing tissues and teeth, and correct the facial structures.
