NCT06783595

Brief Summary

The study will examine the temporary volumetric change that happens in the gums around an implant crown when the crown is removed. The main question of the study is "how much time has to pass to see a significant change, especially when there could be a need to make a mold of the surrounding gum to make a new crown?" The area of the implant crown will be scanned with an intra-oral scanner over a period of 15 minutes.

Outcome Measures

Primary Outcomes (1)

  • Peri-implant mucosal volumetric change

    The mucosal volumetric change will be a composite measurement of the outside and inside portion of the peri-implant gum area by a 3D analyzing software. The 3D image that has been captured from an intra-oral scan will be analyzed during the time interval mentioned in the study description. This measurement is representing the horizontal change, and will be recorded in millimeters (mm). The critical analysis will be placed as changes from 0.5mm. Any change more than 0.5mm will be considered a large amount of change.

    Change between baseline and 15 minutes post initial crown removal

Secondary Outcomes (1)

  • Vertical gingival margin discrepancy

    Change between baseline and 15 minutes post initial crown removal

Interventions

Device that scans the mouth with by taking numerous pictures of the mouth and stitches them together to form a three-dimensional copy of the patient teeth.

Study Population

Patients selected for the participation in the study will be solely from the Center of Implant Dentistry at Loma Linda University School of Dentistry.

You may qualify if:

  • Patient must have a maxillary anterior immediate implant and provisionalization treatment completed.
  • The adjacent tooth next to the implant should be a natural tooth
  • The temporary crown must have been in place for a minimum of 4 months
  • The patient needs to be of general good health, with no significant medical history or social habits that might directly affect the hard and soft tissue
  • Patient must have generally good oral hygiene without any history of gum disease or gum recession of other teeth around the region of interest

You may not qualify if:

  • Patient with an implant crown that has no teeth next to the implant crown
  • Patients who have an active gum disease
