NCT05235048

Brief Summary

It is unclear what is the best approach to implant site development after tooth extraction when the pathology leading to extraction has damaged the alveolus. The main objective of this study is to assess if socket preservation and/or reconstruction surgery provides a clinical benefit in terms of ability to place an implant in a prosthetically guided position in such clinical conditions. The PICO question therefore is: In patients requiring single tooth extraction what is the benefit of socket preservation/reconstruction surgery with respect to spontaneous healing in terms of feasibility and ease of implant surgery?

Outcome Measures

Primary Outcomes (2)

  • Possibility to place dental implant

    The possibility to place a dental implant in a prosthetically driven position (with or without bone or soft tissue augmentation) 16-20 weeks after tooth extraction will be evaluated with a dedicated planning software using cone beam CT data and and digital scanning according to standard clinical practice

    16-20 weeks

  • Surgeon's confirmation of the ability to place a dental implant

    Confirmation during the surgery of the ability to actually insert the implant in a prosthetically driven position with or without the need for soft or hard-tissue augmentation.

    16-20 weeks

Secondary Outcomes (8)

  • Vertical change in bone height at the deepest point in the socket

    16-20 weeks

  • Vertical change in bone height at the buccal bone crest

    16-20 weeks

  • Vertical change in bone height at the crest of adjacent teeth

    16-20 weeks

  • Radiographic bone changes

    16-20 weeks

  • Change in keratinized tissue width between baseline and insertion of prosthetic crown

    16-20 weeks

  • +3 more secondary outcomes

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Systemically healthy. No contraindications to elective oral surgery
  • All pathologies requiring single tooth extraction with adjacent teeth (or implant) with the presence of at least one third of the alveolus.
  • Evidence of subject ability to achieve good oral hygiene and control gingivitis in the whole of the dentition (FMPS\<25% and FMBS\<25%)
  • Ability to understand study procedures and to comply with them for the entire length of the study. Ability and willingness to give informed consent.

You may not qualify if:

  • Presence of frank purulence or acute abscess at the time of extraction
  • Presence of bone resorption of one or more walls of the alveolus extending to the apical third of the socket
  • Self reported current smoking exceeding 20 cigarettes/day or pipe or cigar smoking
  • Presence of medical contraindications to elective surgery
