Treatment Outcome of Two Adjacent Implant-Supported Restorations with Different Implant Platform Designs in the Esthetic Region: A Five-Year Randomized Clinical Trial.

Purpose: The aim of this study was to evaluate the peri-implant soft and hard tissues and satisfaction in patients with two adjacent implant-supported restorations in the esthetic region, treated with two adjacent implants with a scalloped or flat platform.

Materials And Methods: The randomized clinical trial consisted of 40 patients allocated to either a scalloped implant group consisting of 20 patients or a flat implant group of 20 patients. Clinical and radiographic examinations were performed during a 5-year followup period, and patient satisfaction during the same period was assessed.

Changes in crestal bone around endosseous implants during functional loading: a radiographic evaluation in edentulous patients comparing different implant designs.

Marginal bone changes around titanium plasma-sprayed implants (n = 240) placed in the mandibular interforaminal regions of 120 edentulous patients were assessed over 5 years of follow-up, with emphasis on the influence of the locations of the microgap and rough/smooth border. Marginal bone changes were measured on standardized radiographs. Locations of the microgap and the rough/smooth border were both shown not to be major contributing factors in determining the marginal bone level around implants.

Single implants with different neck designs in the aesthetic zone: a randomized clinical trial.

Objectives: To compare single implants in the aesthetic zone with different neck designs for marginal bone-level changes and clinical outcome measures.

Materials And Methods: Ninety-three patients with a missing anterior tooth in the maxilla were randomly assigned to be treated with an implant with a 1.5 mm smooth neck ("smooth group"), a moderately rough neck with grooves ("rough group") or a scalloped moderately rough neck with grooves ("scalloped-group").

Posterior mandibular residual ridge resorption in patients with overdentures supported by two or four endosseous implants in a 10-year prospective comparative study.

Purpose: The aim of this study was to evaluate the effect of treatment with either two or four mandibular endosseous implants with an overdenture on mandibular posterior residual ridge resorption over a 10-year period.

Materials And Methods: Sixty edentulous patients with residual mandibular height between 12 and 18 mm participated. Thirty patients were treated with an overdenture supported by two IMZ implants (group A) and 30 patients were treated with an overdenture with four IMZ implants (group B).

Treatment outcome of two adjacent implant crowns with different implant platform designs in the aesthetic zone: a 1-year randomized clinical trial.

Aim: To evaluate the peri-implant tissues in patients with two adjacent implant crowns in the aesthetic zone, treated with either two adjacent implants with a scalloped platform or with a flat platform.

Material And Methods: Forty patients were randomly allocated to: (1) a "scalloped implant group": 20 patients treated with two adjacent implants with a scalloped platform, and (2) a "flat implant group": 20 patients treated with two adjacent implants with a flat platform. Clinical and radiographic examinations were performed during a 1-year follow-up period to assess hard and soft tissue changes.

Dental implant treatment for two adjacent missing teeth in the maxillary aesthetic zone: a comparative pilot study and test of principle.

Aim: The aim of this prospective comparative pilot study was to evaluate hard and soft peri-implant tissues in patients with a missing adjacent central and lateral upper incisor treated with either one implant and an implant crown with a cantilever or two implants with solitary implant crowns up to 1 year after functional loading.

Material And Methods: In the "Implant-cantilever group", five patients were treated with one dental implant in the region of the central incisor (NobelReplace Groovy Regular Platform). In the "Implant-implant group", five patients were treated with two adjacent dental implants: at the position of the central incisor (NobelReplace Groovy Regular Platform) and at the position of the lateral incisor (NobelReplace Groovy Narrow Platform).

Treatment outcome and patient satisfaction with two adjacent implant-supported restorations in the esthetic zone.

The purpose of this study was to evaluate the clinical and radiographic parameters as well as the esthetic outcome of two adjacent implant-supported restorations and the surrounding peri-implant mucosa in the maxillary esthetic zone. Ten patients were treated with two adjacent implants in the anterior maxillary zone according to the same protocol. Only patients who had been subjected to a separate previous augmentation procedure with autogenous bone were included in this study.
