Efficacy of a Ready Made Plastic Stent With Apically Repositioned Flap in Augmentation of the Peri Implant Soft Tissue

May 4, 2021 updated by: ahmed hamdy mahmoud, Ain Shams University

Effect of Using a Ready Made Plastic Stent With Apically Repositioned Flap in Augmentation of the Peri Implant Soft Tissue Randomized Clinical Study

Keratinized gingiva around dental implants are necessary to achieve esthetic appearance in the anterior teeth, also it is more resistant to abrasion, recession, less in plaque accumulation and inflammation, and easy to manipulate during stage two surgery and impression making in prosthetic stage. For the aforementioned reasons over year's authors have developed many techniques to increase the amount of keratinized gingiva around the dental implants such techniques are apically and laterally repositioned flaps , free gingival grafts, acellular dermal matrix allograft , coronally repositioned flap and sub epithelial connective tissue flaps . Huh et al compared the effects of the use of a ready-made plastic stent on the width of peri-implant keratinized mucosa with those of conventional methods. In addition, the effect of a plastic stent on peri-implant soft tissue was examined through histological observations. Reported that the width of the keratinized mucosa was significantly higher and the distance from the top of the implant platform to the mucogingival junction was significantly longer in the ready-made plastic stent group.

Thus this study will be performed to compare between the effect of the use of a ready- made plastic stent on the width of peri-implant keratinized tissue and that of conventional methods during first stage of implant surgery.

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

This prospective clinical study will be conducted on Twenty patients will be selected from the outpatient clinic of Oral Medicine, Periodontology, and Oral Diagnosis department, Faculty of Dentistry, Ain Shams University This methodology will be reviewed by Ain shams university, faculty of dentistry research ethics committee

Inclusion criteria:

  1. Healthy adult patients as evidenced by Burkett's oral medicine health history questionnaire.
  2. Both genders.
  3. Age from 20 -50 years old.
  4. Having at least one missing tooth at Posterior area (premolars or molars).
  5. Attached gingiva width below 3 mm.
  6. Patient should agree to sign a written consent after the nature of the study will be explained.

Exclusion criteria:

  1. Smokers ( >10 cigs/day ) .
  2. Vulnerable groups (as pregnant females and decisional impaired individuals) will be excluded from the study.
  3. Patients with poor oral hygiene or not willing to perform oral hygiene measures.
  4. Prisoners and handicapped patients.
  5. Patients with periodontal or periapical infections.

Patients met the eligibility criteria will be randomly allocated using computer assisted randomization through numbered sealed envelopes into two treatment modalities groups: -

Group I (with ready-made plastic stent): Will include 10 patients where combined full / partial thickness apically repositioned flap with paracrestal lingual incision will be performed for implant placement followed by healing abutment placement covered by ready-made plastic stent.

Group II (control): Will include 10 patients where combined full / partial thickness apically repositioned flap with paracrestal lingual incision will be performed for implant placement followed by healing abutment placement then suturing the flap in place.

All patients will receive healing abutments in first stage of implant surgery.

This proposal will be reviewed by the research ethics committee, the procedure will be fully explained to the patients and they will sign an informed consent

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.
