March 30, 2022 updated by: Guoli Yang, The Dental Hospital of Zhejiang University School of Medicine

Clinical Application Strategies of Maxillary Sinus Buccal Bony Window With Different Residual Bone Heights in Lateral Maxillary Sinus Floor Elevation

Through randomized controlled trials, investigators will recruit participants who need maxillary sinus floor elevation with different residual bone height, and utilize the maxillary sinus buccal bony window during the surgery. Then investigators will gather the related information of participants, collect and analyze their CBCT data, in order to help surgeons select the best operating method for different patients.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

Through randomized controlled trials, investigators will recruit 60 participants who need maxillary sinus floor elevation with different residual bone height (0~3mm; 3~5mm), and utilize the maxillary sinus buccal bony window during the surgery (A: ground into pieces; B: replace the bone; C: turn inward to hold up the membrane). Then investigators will gather the related information of participants, collect and analyze their CBCT data, in order to help surgeons select the best operating method for different patients.

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

No

Genders Eligible for Study

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
ABH change
Time Frame: baseline, 6 months, and 1, 2, 3, 5, 10 years after the surgery
Apical bone height (ABH): Represented the grafted height at baseline and the grafted height with neo-formed bone at follow-ups.
baseline, 6 months, and 1, 2, 3, 5, 10 years after the surgery
ESBG change
Time Frame: baseline, 6 months, and 1, 2, 3, 5, 10 years after the surgery
Endo-sinus bone gain (ESBG): ESBG = ABH + implant protrusion length at baseline; ESBG represented the grafted height and neo-formed bone, and described the height difference of radiopaque area in the sinus cavity at different times.
baseline, 6 months, and 1, 2, 3, 5, 10 years after the surgery
