Adhesion of Connective Tissue Around Laser-treated Abutments for Dental Implants - Clinical Trial in Humans

University of Barcelona

Status and phase: Unknown; Phase 4

Conditions: Periimplantitis

Treatments: Procedure: Dental implant placement with a final prosthetic abutment

Study type: Interventional

Funder types: Other; Industry

Identifiers

NCT01954485

Laser-Lok® abutment

Details and patient eligibility

About

This study aims to demonstrate the histological differences in the connective tissue surrounding laser-treated abutments and untreated abutments in humans.

Working hypothesis: There are differences in the adhesion of collagen fibres around implant abutments with laser-produced microgrooves and standard abutments.

Full description

All patients will receive both abutment systems. The assignment of the abutments to each of the implants will be made randomly using SPSS 15.0 (SPSS Inc., Chicago, Il, United States) software.

Sex: All

Ages: 18 to 80 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• patients that have scheduled treatment for the placement of at least 2 implants
• patients with favourable attached gingiva
• patients without systemic diseases that would prevent the emplacement of implants
• patient must accept participation in the study by signing an informed consent form

Exclusion criteria

• smokers of 1 or more cigarettes per day
• patients who suffer from any known condition that could be an absolute or relative contraindication to dental implant placement
• patients requiring any additional surgical technique for bone or gum graft in order to insert the dental implant
• patients who refuse to be included in the study or do not sign the informed consent form
