Outcome Measures

Primary Outcomes (4)

  • Pain Evaluation

    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

    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

    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

    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.

    6 months

Study Arms (2)

Moldable self-hardening biphasic calcium phosphate graft

EXPERIMENTAL

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

No graft material

PLACEBO COMPARATOR
Procedure: No graft material placed - Blood Clot only

Interventions

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.

Moldable self-hardening biphasic calcium phosphate graft

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.

No graft material
