Evaluation of esthetic outcome of delayed implants with de-epithelialized free gingival graft in thin gingival phenotype with or without immediate temporization: a randomized clinical trial.
Aim: The current study investigates the effect of immediate temporization on the pink esthetics of delayed implants in patients with thin gingival phenotype in combination with a De-epithelialized Free Gingival Graft in the maxillary premolar area.
Methodology: The study population was randomly assigned into two groups. The two groups were treated with delayed implants with simultaneous placement of a de-epithelialized free gingiva graft. The test group was immediately temporized while the control group had no temporization. The pink esthetic score was assessed as the primary outcome. Additional secondary outcomes were assessed such as the keratinized tissue width and the soft tissue thickness.
Results: Twenty implants were placed in the current study, split into 10 implants per group. The results showed that the Pink Esthetic Score of the IT group was 11.88 ± (1.13) and 11.33 ± (1.25) for the CTG group, which showed no statistical difference between the groups after 1 year of follow-up. There was also no significant difference between the two groups at 12 months regarding the keratinized tissue width and the soft tissue thickness.
Conclusions: Immediate and delayed temporizations have no effect on the Pink Esthetics of the delayed implants; however, immediate temporization allowed earlier provisional crown delivery. Soft tissue augmentation of the thin gingival phenotype improved esthetics for both groups. Trial registration Name of the registry: clinicaltrials.gov; trial registration number: NCT03792425.
