Clinical Trial Summary

Objective: The aim of this randomized clinical trial was to compare ceramic and titanium implants with respect to the esthetic and clinical parameters, and patient reported outcome measures (PROMs).

Material and methods: Thirty patients received thirty implants (8-12 mm in length, 3.3 mm diameter and a tissue level design) to replace the absence of a single tooth in the anterior maxilla. Patients were randomly allocated to receive a ceramic or a titanium implant. Esthetic and clinical parameters and PROMs were evaluated 18 months after surgery.

Description:

The study was a double-blind randomized controlled clinical trial (RCT), with a parallel design, comparing ceramic (test group) and titanium (control group) implants, for the replacement of a single-tooth in the anterior maxilla.

All patients were randomized and assigned to each of the study groups through a computer-generated randomization.

Surgical and restorative procedures In the test group, a Tissue Level Ceramic monotype implant was placed (Straumann PURE Ceramic implants®; Institut Straumann, Basel, Switzerland) and in the control group a Tissue Level SLA Titanium implant (Straumann Standard Plus Narrow Neck CrossFit®; Institut Straumann, Basel, Switzerland). The length of the implants was 8, 10 and 12 mm.

The primary outcome was the Implant Crown Aesthetic Index (ICAI). It consists of nine sections: mesiodistal dimension of the crown, position of the incisal edge of the crown, labial convexity of the crown, color and translucency of the crown, crown surface, position of the gingival margin of the peri-implant mucosa, position of the interdental papilla, contour of the vestibular mucosa and color and surface of the vestibular mucosa. These sections were compared with the adjacent and contralateral tooth as a reference and assigned the following score: 0, excellent; 1 or 2 satisfactory; 3 or 4 moderate; 5 or more bad.

Primary	The primary outcome was the Implant Crown Aesthetic Index (ICAI).	It consists of nine sections: (i) mesiodistal dimension of the crown, (ii) position of the incisal edge of the crown, (iii) labial convexity of the crown, (iv) color and translucency of the crown, (v) crown surface, (vi) position of the gingival margin of the peri-implant mucosa, (vii) position of the interdental papilla, (viii) contour of the vestibular mucosa and (ix) color and surface of the vestibular mucosa. These sections were compared with the adjacent and contralateral tooth as a reference and assigned the following score: 0, excellent; 1 or 2 satisfactory; 3 or 4 moderate; 5 or more bad (Meijer et al., 2005).	36 months
