Oral rehabilitation of tooth agenesis frequently starts in paediatric dentistry. A retrospective analysis of 625 patients.

Aim: As oral rehabilitation of tooth agenesis usually begins at a very young age, it is important to plan the therapy in advance in order to prepare the patient for the final treatment after the end of skeletal and dental growth. The diverse patterns of tooth agenesis require interdisciplinary oral rehabilitation adapted to individual factors like patient's age, number of missing teeth, and alveolar-bone development. The aim of the present high volume single-center study was to provide an overview of the management of patients with tooth agenesis, in terms of treatment approaches, associations, and long-term implant survival, over a period of 30 years.

Patterns of congenitally missing teeth of non-syndromic and syndromic patients treated at a single-center over the past thirty years.

Objectives: Literature regarding congenitally-missing-teeth (CMT) is lacking especially on CMT-patterns. Thus, the aim of this study was to present an in-depth analysis of 843 patients with CMT treated at a single-center over the past thirty years.

Design: Age, date-of-birth-year, gender, medical- and family-history, CMT-types, -numbers, -severity, -region, -symmetry, -patterns using the tooth agenesis code (TAC), and -growth types of all clinically and radiographically diagnosed CMT-patients were collected.

Does osteoporosis influence the marginal peri-implant bone level in female patients? A cross-sectional study in a matched collective.

Background/purpose: Osteoporosis, being a homeostatic imbalance, affects the remodeling of bone. Whether this catabolic bone disease influences peri-implant marginal bone remodeling remains unknown so far. The purpose of this study was to evaluate the influence of osteoporosis on peri-implant marginal bone loss (MBL) in postmenopausal women.

Effectiveness of subperiosteal bone anchor (Onplant) placement in the anterior highly atrophic maxilla for cross-arch prosthetic rehabilitation: Results from a pilot study.

Purpose: The present prospective pilot study aimed to evaluate the feasibility of Onplants (Onplant Orthodontic System) off label use in the highly atrophic edentulous maxillae of adult patients to avoid bone grafting and conventional dental or zygomatic implants.

Material And Methods: Two Onplants were placed subperiosteally in the anterior part of the hard palate in five adult patients presenting a highly atrophic edentulous maxilla, class V or VI, according to Cawood and Howell. After a healing period of 4 months the prosthetic procedures were started.

Dental implants are a viable alternative for compensating oligodontia in adolescents.

Objectives: To clinically and radiographically evaluate dental implant treatment in adolescents with extensive oligodontia.

Methods: Patients with more than nine permanent teeth congenitally missing and implant treatment before the age of 16 years were included. Clinical follow-ups involved bleeding on probing, plaque index and peri-implant probing value.
