Summary

The aim of a study was to analyze the effect of implant placement depth (4 mm versus 6 mm below the mid-facial gingival margin) on marginal bone loss (MBL) around implant and implant stability during immediate implant placement after tooth extraction. Clinical trial was conducted involving 35 patients requiring immediate implant placement after tooth extraction. Implants were placed either 4 mm (control group) or 6 mm (test group) below the mid-facial gingival margin. Primary outcome was deemed to be radiographic assessment of marginal bone level from periapical radiographs. Secondary outcome was implant stability quotient registration using resonance freaquency analyzer. The null hypothesis is that there is no significant difference in peri-implant marginal bone loss between implants placed at 4 mm depth versus 6 mm depth relative to the buccal gingival margin during immediate implant placement.

Conditions

  • Dental Implant
  • Tooth Extractions
  • Marginal Bone Loss Around Implants
  • Primary Stability of the Implants

Interventions

PROCEDURE

Implants were positioned 4 mm below the mid-facial gingival margin

Tooth was carefully extracted and implant was placed 4 mm below free gingival margin of the extracted tooth.

PROCEDURE

Implant was placed 6 mm below free gingival margin

Tooth was extracted and dental implant placed 6 mm below free gingival margin of the extracted tooth.
