入选标准
- •Patients with remaining roots in the esthetic zone with intact periodontal condition indicated for extraction.
- •Physically able to tolerate conventional surgical and restorative procedures
- •Signing of an informed consent form
- •Implant insertion torque > 32 N cm with good primary stability
排除标准
- •Systemic diseases contraindicating implant placement eg uncontrolled diabetes
- •Severe bruxism
- •Active infection in the teeth to be treated
- •Vertical root fractures with displacement in the teeth of the surgical area
研究组 & 干预措施
socket shield (A)
- Following local anesthetic infiltration opposite to the root to be extracted the root is sectioned in a mesiodistal direction along its long axis as far apical as possible.
- After sectioning the root into labial and palatal halves, the palatal half is removed with preservation of the labial root section.
- The labial half is prepared to be Flushing or 1mm above the labial alveolar crest. Then thinned slightly to a concave contour in an apico-coronal and mesiodistal direction.
- The implant will be inserted in place of the palatal half with the labial surface of the implant facing the labial root shield (root-implant interface)
primary closure will not be attempted as the patients will undergo immediate non-functioning provisionization.
干预措施: implant placement (Procedure)
conventional immediate implant (B)
- Following local anesthetic infiltration opposite to the root to be extracted non traumatic extraction of the tooth or remaining root by periotome.
- The implant fixture will be inserted in the empty socket by conventional manner.
primary closure will not be attempted as the patients will undergo immediate non-functioning provisionization.
干预措施: implant placement (Procedure)
