Two Stage Modified Socket Shield: Grafted vs Nongrafted

NCT07460648 | Completed DMC

• 1 other identifier: R.26.02.109
• Study Type: interventional
• Target: 24
• Locations: 1 country
• Sites: 1

Brief Summary

Modified socket shield therapy (SST) has been proposed to preserve the facial plate and peri implant tissues. Whether spontaneous healing after two stage modified SST provides outcomes comparable to grafted SST before delayed implant placement remains unclear.

Conditions

Socket Shield Technique Implant Placement; Socket Shield Technique; Dental Implant; Bone Grafting; Delayed Implant

Keywords

Modified socket shield; Delayed implant placement; Xenograft; Mineralized plasmatic matrix; Histomorphometry; Implant stability; Socket shield technique

Outcome Measures

Primary Outcomes (2)

• Soft tissue ingrowth dimension: depth

  Soft tissue ingrowth dimensions; depth and width were measured using a calibrated periodontal probe with readings taken to the nearest millimeter and rounded up when the probe reading reached or exceeded the midpoint between millimeter markings. Depth (mm) was recorded from the most coronal aspect of the retained root fragment and measured apically until hard tissue was encountered.

  6-month (at the time of implant placement)

• Soft tissue ingrowth dimension: width

  Width (mm) was measured in a buccopalatal direction from the central aspect of the socket shield to the point where hard tissue was reached, representing the maximum diameter of the soft tissue ingrowth.

  6-month (at the time of implant placement)

Study Arms (2)

Control Group

EXPERIMENTAL

Socket Shield Technique alone with spontaneous healing

Procedure: Socket Shield Technique

Test Group

EXPERIMENTAL

Socket Shield Technique with MPM augmentation

Procedure: Socket Shield Technique

Interventions

Socket Shield Technique PROCEDURE

No grafting material was placed, and the socket was closed with a figure-of-eight suture to stabilize the clot
