A study of 184 consecutive patients referred for single-tooth replacement.

The aim of this investigation was to study the acceptance and the rejection of patients referred for single implant restorations based on data from referral, case history, clinical examination and therapy planning. The referrals comprised 184 patients with 251 missing single teeth. Sixty-four per cent of the referred patients were accepted for treatment.

Anterior tooth replacement with implants in patients with a narrow alveolar ridge form. A clinical study using guided tissue regeneration.

Clinical and radiographic examination was used to select patients with a suspected need of guided tissue regeneration (GTR). Fifteen patients with 20 fixtures were included in the study. Nine (45%) of the fixtures were completely covered with bone at fixture surgery and no GTR was required in these cases.
