Purpose:
To introduce the method of extracted site preservation in dental implantation.
Methods:
One hundred and fifty implants in 63 patients were placed by minimally invasive extraction, immediate implantation and guided bone regeneration for extracted site preservation. All the patients were followed-up for 1 year.
Results:
(1) One hundred and fifty implants were placed successfully according to the criteria. (2) Alveolar ridge of extracted site preservation reduced 1 mm in height, buccal-lingual distance in alveolar ridge of extracted site reservation reduced 2 mm; (3) The shape of soft tissue was symmetrical.
Conclusions:
Minimally invasive extraction, immediate implantation and guided bone regeneration technique can be used to achieve extracted site preservation, which is the key to successful implantation.
