Short-term effect of titanium abutment versus zirconia abutment on peri-implant tissues in anterior teeth

Abstract

Abstract:

BACKGROUND: With the increasing aesthetic pursuit of patients, an aesthetic abutment with certain strength has aroused people’s attentions either in the anterior or posterior tooth repair.

OBJECTIVE: To evaluate the effects of titanium abutment and zirconia abutment on peri-implant tissue in anterior teeth.

METHODS: A total of 40 anterior teeth from 34 patients were selected and received single crown restoration with Ankylos implants. Among them, titanium abutments were used in 20 teeth, and zirconia abutments in the other 20 teeth. All the patients were re-visited at 12 months after crown restoration. Peri-implant marginal bone resorption length (MBL), periodontal probing depth (PD), modified plaque index (mPLI), modified sulcus bleeding index (mSBI), and papilla index (PP) were detected; patient satisfaction investigation was carried out; and aesthetic assessment was done based on the pink esthetic score (PES).

RESULTS AND CONCLUSION: There were no differences between two groups in MBL, PD, mPLI, mSBI, PP. Patients in both groups were satisfied with the treatment outcomes with insignificant difference (P > 0.05). The PES value in the zirconia abutment group was significantly higher than that in the titanium abutment group (P < 0.05). Overall, titanium and zirconia abutments show the similar effects on the peri-implant tissues and both can achieve good clinical outcomes. However, zirconia abutments have certain advantages in the aesthetic restoration for anterior teeth, and further investigation on long-term effects is warranted.
