Pink Esthetic Score Around Immediate Implants Using PDDM as Jumping Gap Filling Material.

Not Applicable

Not yet recruiting

Brief Summary: Will there be a difference in Pink Esthetic score and soft tissue changes around immediate implants in maxillary esthetic zone following grafting the jumping gap with partially demineralized dentin matrix compared with xenograft?

Detailed Description: This study aims to evaluate the soft tissue changes as well as hard tissue changes around immediate implants in maxillary esthetic zone following grafting the jumping gap with partially demineralized dentin matrix in comparison to xenograft.

Because xenogeneic bone is so readily available in substantial quantities, it has been the subject of notable research. However, because they contain organic material from a foreign species, xenogeneic bones are inherently very antigenic.

According to experimental results, PDDM encourages bone regeneration in a manner like autogenous bone. Both cortical bone and autogenous tooth grafts share similar physical and chemical characteristics, including optimal biodegradability, not requiring a separate surgery to harvest the graft and space maintenance capabilities. PDDM is a valuable comparator to autogenous bone in ARP and around dental implants in guided bone regeneration procedures

Recruitment & Eligibility

Arm && Interventions

Group	Intervention	Description
Partially demineralized dentin matrix graft	Immediate implant	* A high-speed fine finishing stone and saline irrigation will be used to clean extracted teeth from periodontal ligaments, soft tissue attachments, caries, and restorations if present. * Teeth particles will be partially demineralized using nitric acid 2% for fifteen minutes. * Finally, the prepared partially demineralized dentin matrix graft granules will be washed twice with distilled water and phosphate buffered saline * Immediate implant of appropriate dimensions will be placed and the previously prepared partially demineralized dentin matrix graft will be used to graft the jumping gap. * Customized healing abutment will be used. * In Osseo integrated implants temporary abutment will be removed and impressions for final restoration will be performed after 3 months.
xenograft	Immediate implant	* After tooth extraction, thorough curettage will be performed. * Immediate implant of appropriate dimensions will be placed, and the jumping gap will be grafted with xenograft "Cerabone" . * Customized healing abutment will be used. * In Osseo integrated implants temporary abutment will be removed and impressions for final restoration will be performed after 3 months.

Primary Outcome Measures

Name	Time	Method
Pink esthetic score	twelve months after final restoration	a fourteen point scale to evaluate pink esthetics. The pink esthetic score (PES) estimates the esthetic results of soft tissue surrounding the implant with regarding 7 points : mesial, distal papilla, soft tissue margin, soft tissue contour, alveolar process, colour, texture. the score of zero will be lowest and two will be the highest for each of the seven points with zero being the lowest and 14 being the highest.

Secondary Outcome Measures

Name	Time	Method
Patient satisfaction	one year after final restoration	a twelve point questionnaire to evaluate patient satisfaction
Vertical and horizontal radiographic changes in bone dimensions	immediate post operative and twelve months after final restoration	cone beam CT will be used to detect vertical and horizontal changes
Midfacial mucosal alteration	preoperative and twelve months after final restoration	rubber base impressions taken before the surgical procedure and 12 months after implant restoration. Then, casts were poured with type IV die stone and optically scanned. The obtained models were compared by digital superimposition in a matching software to measure the vertical alterations of the buccal peri-implant soft tissue.
