NCT05107141

Brief Summary

The objectives of the present investigation are; to compare the dimensional changes and the histological composition after the use of an allograft or xenograft and a resorbable membrane in ridge preservation in molar sites, to evaluate the influence of bone plates thickness on dimensional changes and the effectiveness of ridge preservation in limiting the need of sinus elevation.

Outcome Measures

Primary Outcomes (1)

  • Evaluation of ridge dimensional changes following ridge preservation in molar sites comparing the use of freeze dried bone allograft (FDBA) or xenograft (DBBM), and a resorbable membrane.

    To evaluate dimensional changes, the initial (CBCT1) and 5 months (CBCT2) CBCT images were processed and superimposed with the use of a specialized software image Simplant® O\&O (Denstply Sirona, Charlotte, NC, USA). Measurements were expressed in millimeters (mm) and percentages showing changes in ridge width at 1mm, 3mm and 5mm from the bone crest. The height of the buccal, and lingual bone crest was assessed, as well as the heigh in the central are of the socket.

    5 months

Secondary Outcomes (2)

  • Evaluate the influence of buccal or lingual bone thickness on bone ridge changes

    5 months

  • Evaluate the histologic composition of the regenerated areas after the use of freeze dried bone allograft (FDBA) or xenograft (DBBM), and a resorbable membrane.

Eligibility Criteria

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

You may qualify if:

  • Adult patients, over 18 years old.
  • In need of removal of a maxillary or mandibular molar first or second molar.
  • The molars to be extracted had to be bordered by at least one tooth.
  • The molars had to have a presence of \> 2 mm of keratinized gingiva and three intact bony walls.
  • A dehiscence on the fourth wall, if any, had to be equal or less than 2 mm in height.
  • Only one extraction per patient was accepted.

You may not qualify if:

  • Acute periodontal or periapical infection.
  • Pregnancy or lactancy.
  • Smokers of more than 10 cigarettes per day.
  • Previous adverse reactions to the biomaterials used in the study.
  • Metabolic diseases affecting the mechanism of bone remodelling.
  • Medications or treatments taken in the last twelve months and known to affect bone "turnover".
  • Patients with poor plaque control -more than 20% (O'Leary, Drake, Naylor, 1972).
  • Patients with absence of periodontal health maintenance or postoperative recommendations compliance.
