NCT02660697

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Orovestibular socket dimension

    On prealigned pre- and postoperative CBCT cross-sections, linear measurements were taken parallel to a reference base to determine the orovestibular width of extractions sites

    From baseline to 6-9 months postoperatively

Secondary Outcomes (3)

  • Minimal orovestibular socket dimension feasible for implant placement

    From baseline to 6-9 months postoperatively

  • Vertical socket dimension

    From baseline to 6-9 months postoperatively

  • Socket area

    From baseline to 6-9 months postoperatively

Study Arms (2)

Test - Extraction site development group

ACTIVE COMPARATOR

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.

Procedure: Extraction site development

Control - Spontaneous healing group

NO INTERVENTION

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.

Interventions

In the test group, extraction sockets presenting EDS Type 3-4 buccal bony dehiscences were treated by a novel minimally invasive tunnelised modified GBR approach (XSD).
