Study Details

Study Description

Brief Summary

this study is aiming to Assess postoperative complications and bone quality and quantity in augmentation of horizontally atrophic maxillary ridge using a 1:1 mixture of autograft and xenograft particulate bone covered with collagen membrane with the new Sausage technique™ versus using the same mixture covered with titanium mesh.

Condition or Disease	Intervention/Treatment	Phase
Horizontal Ridge Deficiency	Procedure: titanium mesh Procedure: collagen membrane (Sausage technique)	N/A

Detailed Description

patients with atrophic maxillary ridge < 4 mm will be selected in this study for augmentation for future implant placement. The full thickness flap will be elevated including one extra tooth on each side of the edentulous area or if completely edentulous 5 mm on each side.. the bone bed will be prepared by cleaning any debris and Multiple decortication holes will be performed with a 2.0 mm round bur. the harvested bone from the chin is then mixed with the xenograft with ratio 1:1 and then put on the recipient site and will be covered with a collagen membrane with the Sausage technique (intervention group) and the other group the graft will be covered with titanium mesh (control group).

flap is repositioned and sutured. followup for 6 months and then CBCT is done. Reopening after 6 months, core biopsy is taken by a 2 mm thickness trephine from the healed augmented bone at the site of implant placement and will be sent for histomorphometric analysis and the bone thickness (buccolingual ) dimension is measured using a caliper and from the CBCT (cone beam CT) the bone width gain will be calculates and recorded.

postoperative complications( infection, wound dehiscence or membrane exposure) will be monitored and recorded.

Study Design

Study Type:

Interventional

Anticipated Enrollment :

20 participants

Allocation:

Randomized

Intervention Model:

Parallel Assignment

Intervention Model Description:

the participants are divided into two groups one control and the other is the interventionthe participants are divided into two groups one control and the other is the intervention

Masking:

None (Open Label)

Masking Description:

because the two interventions used in this trial are clearly different and easily recognized by the investigator and the participants. neither the participant nor the investigator could be blinded

Arms and Interventions

Arm	Intervention/Treatment
Active Comparator: titanium mesh using non resorbable titanium mesh to fix and cover the onlay bone graft mixture to the atrophic maxillary ridge.	Procedure: titanium mesh the non resorbable titanium mesh is used to fix the 1:1 mixture of autograft and xenograft particulate bone on the severely atrophies maxillary ridge.
Experimental: collagen membrane(Sausage technique) using resorbable collagen membrane with the sausage technique to fix the onlay bone graft mixture to the resorbed atrophic maxillary ridge	Procedure: collagen membrane (Sausage technique) the resorbable collagen membrane is used to fix the 1:1 mixture of autograft and xenograft particulate bone on the severely atrophies maxillary ridge.

Outcome Measures

Primary Outcome Measures

membrane exposure [within 3 weeks]
clinical postoperative complications as flap dehiscence and membrane exposure into the oral cavity, its a binary outcome (yes/No) examined and recorded by the investigator.
infection [10 days]
suppuration collection related to the membrane and flap, its a binary outcome (yes/No) examined and recorded by the investigator.
inflammation [10 days]
redness and tenderness of the flap, its a binary outcome (yes/No) examined and recorded by the investigator.

Secondary Outcome Measures

bone width gain [at 6 months]
the amount of bone gained( in millimeter) after augmentation compared to the initial ridge thickness measured clinically using a caliper 2 mm below the crest of the ridge, and radiographically using the Planmeca Promax 3D CBCT unit which will be viewed on planmeca romexis software to calculate the measures needed in millimeter by the outcome assessor.
bone quality [at 6 months]
histomorphometric analysis of the bone biopsy taken from the augmented bone to show the quality of the formed bone and the percentage of every type of tissue formed in the specimen taken( unit is area percentage %)

Eligibility Criteria

Criteria

Ages Eligible for Study:

18 Years and Older

Sexes Eligible for Study:

All

Accepts Healthy Volunteers:

Yes

Inclusion Criteria:

Patients with horizontal atrophied maxillary ridge (thin ridge) less than 4mm.
All ages and both sexes were included in this study.
Patients should be free from any systemic disease that may affect normal healing of bone, and predictable outcome.
Patients with physical and psychological tolerance

Exclusion Criteria:

Patients with high risk systemic diseases like uncontrolled diabetes mellitus. As uncontrolled diabetes mellitus has a negative impact on normal bone healing. 8
Heavy smokers.4
Alcohol or drug abuse
Gingival bleeding or full mouth plaque index ≥ 25%.4
Patients with physical and psychological intolerance. As psychological stress will affect the immune system and patient's fitness including healing capacity. 9
Unavailability for regular follow-ups
