September 14, 2018 updated by: Renzo Guarnieri, University of Roma La Sapienza

Submerged vs. Nonsubmerged Single Laser-microgrooved Implants. Clinical and Radiographic Results at 3-years of RCT With Split Mouth Design.

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Description

Inclusion Criteria:

Inclusion criteria were: age ≥ 18 years, good general health, without contraindications to implant surgery, presence of at least two non-adjacent edentulous sites requiring implant therapy. Each implant site had to be located in the left or right hemi-posterior mandible or in the left or right hemi- posterior maxilla.

Exclusion Criteria:

  • Exclusion criteria were: implants placed into regenerated bone, lack of a periodontal chart and periapical radiograph at the beginning and at the end of follow-up period, alcohol and drug abuse, pregnancy, or uncontrolled metabolic disorders, tobacco smoking (> 10 cigarettes/day), full mouth plaque score (FMPS), and full mouth bleeding score /FMBS) ≥25%, periodontally compromised patients (with attachment loss of 3 mm and/or radiographic bone loss of 30% of root length in 30% of sites), teeth adjacent to the implant area (mesial and distal) affected by untreated periodontal and/or endodontic infections.
