Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Aim: to evaluate and compare radiographic marginal bone loss (MBL) and soft tissue parameters around submerged/two-stage and nonsubmerged/one-stage single implants with same tapered body design and surface, same thread design and distance, and same collar surface (laser-microgrooved), after 3 years of loading.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Materials and methods: 20 submerged/two-stage implants and 20 nonsubmerged/one stage implants were placed randomly with a split mouth design, in 20 partially edentulous patients. Radiographic and clinical examinations were carried out at the implant placement (Baseline, BSL), at the delivery of prosthetic restorations (T0), and at each year of the follow-up period (T1, T2, T3). Plaque index (PI), probing depth (PD), bleeding on probing (BOP), and gingival recession (REC) were recorded. Radiographic marginal bone levels (MBL) were assessed at the mesial (MI) and distal (DI) aspect of implant sites. In addition, the influence of keratinized tissue thickness (KTT) on MBL was investigated.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

SEQUENTIAL

The cases were randomly divided into two groups as two-stage/submerged, and one-stage/nonsubmerged. Thus, in each patient, the two implants (submerged and nonsubmerged) were placed randomly in the left and right hemi-mandible or in the left and right hemi-maxilla
