About

The present retrospective study aims at assessing the clinical effects of a novel implant site development (Extraction site development - XSD) technique after tooth extraction compared with extraction alone in patients requiring dental implant placement following healing of extraction sockets.

Full description

In advanced (Extraction Defect Sounding Class 3-4) alveolar defects, a minimally invasive tunnelised socket preservation technique utilising long term resorbable membranes and connective tissue grafting was used for extraction site development (XSD). The novel technique was evaluated in a retrospective comparative case series study including a total of 54 extraction sites. In the test group, out of 33 single rooted teeth, 29 in the maxilla and 4 in the mandible were removed, extractions sites were treated by the XSD method. Out of 33 teeth, 27 were incisors, 2 canines and 4 premolars. In the control group, out of 21 single rooted teeth, 11 in the maxilla and 10 in the mandible were extracted and left for spontaneous healing. Out of 21 teeth, 13 were incisors, 2 canines and 6 premolars. CBCT scans were taken prior to tooth extraction and 6-9 months later in both groups. Radiographic evaluation was carried out using the I-CAT Vision (Imaging Sciences International, LLC; Hatfield, USA) and ImageJ (National Institutes of Health) softwares. Following manual alignment of CBCTs vertical and horizontal linear measurements as well as planimetric measurements of cross-section areas were performed in pre- and postoperative data sets at the extraction sites.

43 participants in 2 patient groups

Test - Extraction site development group

Active Comparator group

Description:

In the test group 29 healthy patients presenting 33 single rooted teeth scheduled for extraction with Extraction Defect Sounding (EDS) Class 3-4 type buccal bony dehiscences were included. 29 maxillary single rooted teeth and 4 single rooted teeth in the mandible (27 incisors, 2 canines and 4 premolars) were removed and treated by the novel extraction site development method. Pre- and postoperative ConeBeam Computer Tomography (CBCT) data were collected for further analysis.

Treatment:

Procedure: Extraction site development

Control - Spontaneous healing group

No Intervention group

Description:

In the control group. pre- and postextraction CBCT data sets of 14 patients with 21 extracted teeth were collected. 11 maxillary single rooted teeth and 10 single rooted teeth in the mandible (13 incisors, 2 canines and 6 premolars) were extracted and left for spontaneous healing.
