title: [Clinical application of extracted site preservation in dental implantation].
abstract: OBJECTIVE
  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.
