Clinical Performance of Dentals Implants With Hydrophilic or Hydrophobic Surfaces

May 8, 2023 updated by: Cláudio Rodrigues Leles, Universidade Federal de Goias

Clinical Performance of Dental Implants With Hydrophilic or Hydrophobic Surfaces in Single Posterior Edentulous Spaces: a Randomized Clinical Trial

The aim of the study is to compare longitudinally the clinical performance of dental implants with different surfaces placed in single tooth gaps at the posterior maxilla and mandible of adults. It is a randomized clinical trial, in which participants will be randomly allocated to two groups: test group (implants with hydrophilic surface) and control group (implants with hydrophobic surface). The null hypothesis is that the implant stability quotient of hydrophilic and hydrophobic dental implants show a similar progression after placement in posterior tooth gaps.

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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Present single or multiple intercalated untreated tooth gaps in the posterior region of the mandible or maxilla;
  • Agree to participate in the study by signing the informed consent form.

Exclusion Criteria:

  • Unavailability for participation or signs that they could not comply with the schedule of follow-up visits;
  • Presence of general and/or local contraindications that could prevent the surgical procedure for implant placement;
  • Presence of conditions that may interfere with the prognosis, such as current treatment with bisphosphonates or report of use for less than 2 years, presence of rheumatic diseases, among others;
  • Absence of the minimum bone quantity of 8 mm in length and 3.75 mm in diameter for installation of an implant in the tooth gap;
  • Absence of a mesio-distal space of at least 4.6 mm in the single tooth gap required to place the surgical guide;
  • Do not present a mouth opening of at least 12mm required for the proper of the guided surgical kit together with the surgical guide;
  • Do not present a band of keratinized tissue favorable for maintaining peri-implant health.
  • Present motor difficulties that compromise adequate oral hygiene.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change of implant stability
Time Frame: 10 time-points will be considered and divided in two phases: surgical and prosthetic. The last measure will occur 1 year after the placement of the definitive implant restoration.
Implant stability was set as the primary outcome. The implant stability quotient (ISQ) will be measured using a portable device called Osstell ISQ (Osstell Mentor, Integration Diagnostics, Göteborg, Sweden).
10 time-points will be considered and divided in two phases: surgical and prosthetic. The last measure will occur 1 year after the placement of the definitive implant restoration.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Implant success
Time Frame: Assessed at the 12-month follow-up visit.
Each implant will be assessed according to the health scale of the International Congress of Oral Implantologists (ICOI-Pisa health scale). After clinical assessment, each implant will be classified as 'success', 'satisfactory survival', 'compromised survival' or 'failure'.
Assessed at the 12-month follow-up visit.
Periimplant bone level
Time Frame: Radiographs will be obtained at 4 time points: immediately after implant placement, at the session of the provisional prosthesis installation, and at the 6 and 12-month follow-up visits after the delivery of the definitive prosthesis.
Periapical radiographs will be obtained and the periimplant bone level will be measured and compared longitudinally.
Radiographs will be obtained at 4 time points: immediately after implant placement, at the session of the provisional prosthesis installation, and at the 6 and 12-month follow-up visits after the delivery of the definitive prosthesis.
Condition of the periimplant soft tissues
Time Frame: 15-days, 6- and 12-month follow-up visits after delivery of the definitive prosthesis.
The following parameters will be assessed clinically: presence/absence of bleeding on probing, probing depth, and presence/absence suppuration.
15-days, 6- and 12-month follow-up visits after delivery of the definitive prosthesis.
