Accuracy of Guided Implant Placement Using Double Versus Triple Scan Protocol in Completely Edentulous Patients : Randomized Clinical Trial

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

In this study we discuss linear and angular deviation of actual implant position using planning protocol C1(double scan technique) or C2 (triple scan technique) in completely edentulous patient .

Both protocols C1(double scan technique) and C2 (triple scan technique) indicated in completely edentulous patient and require C.T scan for patient wearing scan appliance .

In C1(double scan technique) , after CT scan for patient wearing scan appliance , two optical scan for the model with and without scan appliance.

In C2 (triple scan technique) , after CT scan for patient wearing scan appliance , CT scan for scan appliance alone .

Teeth positions in both protocols were identified by radio-opaque scan appliance .

16 implant placement by surgical guide using double scan protocol versus triple scan protocol ( two groups - 8 implants in each group ) to Evaluate angular and linear deviation of virtual implants and actual implant position in completely edentulous patients according to scanning protocol C1(double scan technique) and C2 (triple scan technique) .

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

30 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

  1. patients totally edentulous arches.
  2. patients with Bucco-lingual bone thickness >6 mm allowing flapless implant placement
  3. patients free from any systemic diseases that may affect bone quality e.g diabetes.

Exclusion Criteria:

  1. patients with thin ridges.
  2. patients with systemic disease that may affect bone quality.
  3. Patients with poor oral hygiene and active periodontal diseases.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
double scan protocol
In C1(double scan technique) , after CT scan for patient wearing scan appliance , two optical scan for the model with and without scan appliance.
triple scan protocol
In C2 (triple scan technique) , after CT scan for patient wearing scan appliance , CT scan for scan appliance alone .
Diagnostic test: scan protocol
Scanning strategy is based on multiple scans. Essentially one CT scan of the patient (usually with a scan appliance). Another CT scan of the model or scan appliance may be required (double scan technique). Such a second CT scan can be replaced by optical scanning of the model and scan appliance (triple scan technique).

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
Evaluation of angular deviation between planned implants in surgical guide and actual implant position in completely edentulous patients .
Time Frame: immediate post operative
Evaluation of angular deviation between planned implants in surgical guide and actual implant position in completely edentulous patients according to scanning protocol C1(double scan technique) and C2 (triple scan technique) .
immediate post operative

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
Evaluation of linear deviation between planned implants in surgical guide and actual implant position in completely edentulous patients
Time Frame: immediate post operative
Evaluation of linear deviation between planned implants in surgical guide and actual implant position in completely edentulous patients according to scanning protocol C1(double scan technique) and C2 (triple scan technique) .

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Anticipated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
November 20, 2017

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
