Bioabsorbable root analogue for closure of oroantral communications after tooth extraction: a prospective case-cohort study.


Thoma, K; Pajarola, G F; Grätz, K W; Schmidlin, P R (2006). Bioabsorbable root analogue for closure of oroantral communications after tooth extraction: a prospective case-cohort study. Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology and Endodontology, 101(5):558-564.

Abstract

OBJECTIVE: To assess the clinical capacity of a bioabsorbable root analog to close oroantral perforations after extraction. STUDY DESIGN: In this prospective case-cohort study, 20 consecutive patients with oroantral communications greater than 2 mm were treated with a bioabsorbable root analog (RootReplica). Patients were followed up clinically and radiographically for 3 months to monitor the healing process. RESULTS: Root replicas could be placed in 14 patients, whereas 6 patients required the socket to be covered with a buccal sliding flap. In the latter cases, fragmentary roots or overly large defects prohibited replica fabrication or accurate fitting of the analog, respectively. Healing was uneventful in all patients, and epistaxis, swelling, or pain was observed only in patients treated with flaps. CONCLUSIONS: The method described is a valuable alternative method with which to close oroantral communications but cannot be performed in all patients because of technical limitations.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
