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 study was designed as a randomized controlled clinical trial, the study population consisted of 20 patients with missing maxillary posterior teeth and residual bone height 5-7mm. The sample was selected conveniently according to a list of inclusion and exclusion criteria, the participants were allocated randomly into two equal groups. All patients had sinus lift using piezosurgery device with simultaneous implant placement. In group I, blood clot was the only filling material. In group II, moldable, self-hardening calcium phosphate was the filling material. Clinical and radiographic evaluations were done through 6 months postoperatively.

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.

Intervention / Treatment

EXPERIMENTAL: Moldable self-hardening biphasic calcium phosphate graft
Easy graft, a moldable osteocondutive allograft formed of 60% hydroxylapatite and 40% β-tricalcium phosphate (Easy-graft, Sunstar, Gruidor, Degradable solutions AG, Swizerlard).
Other: Moldable self-hardening biphasic calcium phosphate graft
Incision was performed in the canine area then a full thickness mucoperiosteal flap was elevated and exposure of the lateral aspect of the maxillary sinus. Osteotomy of the buccal window was performed using the piezosurgery device followed by meticulous dissection of the sinus membrane. Drilling the site were implants were to be placed, guided by the preformed surgical stent. Implants of appropriate size were torqued to engage the apical aspect of the implant recipient site. The sinus was augmented with moldable self-hardening biphasic calcium phosphate. Repositioning and suturing of the flap using 3-0 black silk suture material.
PLACEBO_COMPARATOR: No graft material
Procedure: No graft material placed - Blood Clot only
A pyramidal full thickness mucoperiosteal flap was performed distal to the canine area with a crestal incision located palatally in the edentulous area and vertical extension of the incision to the buccal vestibule using Bard Parker blade number 15. The flap was reflected exposing the alveolar bone. Lateral window was performed and the sinus membrane was elevated using piezo surgery. Drilling at the sites where implants were to be placed was done using Neobiotech implant drilling Kit. Implants. Implants were placed in a self-tapping fashion using a torque wrench. Flaps were replaced back and sutured using 3-0 black silk suture material.

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
Pain Evaluation
Time Frame: 1 week
Pain was assessed through on a 10-point Visual Analogue Scale (VAS). (0-1= None, 2-4= Mild, 5-7= Moderate, 8-10= Severe)
1 week
Wound healing
Time Frame: 1 week
The presence of alveolar osteitis (dry socket) will be determined clinically using BLUM'S criteria. Wound healing was assessed and recorded depending on the absence or presence of dehiscence, every opening along the incision will be recorded as dehiscence , dental tweezers will be used to identify it.
1 week
Radiographic Evaluation
Time Frame: 6 months
Cone beam computed tomography (CBCT) was done. The apparatus and the settings were kept the same during all the preoperative scans to evaluate the amount of vertical bone height gained, the change of bone density and the marginal bone loss postoperatively.
6 months
Implant stability
Time Frame: 6 months
Examining implant stability was done using Osstell (Osstell co. Swedan). It is a noninvasive and easy-to-use system to determine implant stability and to assess the process of osseointegration.
