BONE GRAFT WITH PLATELET RICH

PLASMA IN CORRECTION OF BONY

DEFECTS IN MAXILLA & MANDIBLE :

A CLINICAL STUDY.

6.BRIEF RESUME OF THE INTENDED WORK

6.1 NEED FOR THE STUDY

Success of graft depends on rate of bone formation & rate of bone resorption.. This in turn depends on revascularisation of graft. Larger part of cancellous bone grafts like iliac bone grafts are revascularised within 2 weeks as compared to the predominantly cortical bone grafts like symphysis bone grafts which when placed alone, take longer periods for revascularization.

That provokes need of certain material that when placed along with cortical graft, will accelerate vascularisation & ultimately accelerate remodelling of graft & according to literature Platelet-rich plasma (PRP) made from autologous blood is most cost effective & least time consuming to obtain.

Need for this study is to access the viability of autogenous mandibular symphysis graft along with platelet rich plasma in enhancing the revascularization & remodeling of graft.

6.2 REVIEW OF LITERATURES

Michael A. Pikos, DDS. Practiced this technique in more than 500 patients & stated that for repair of most localized alveolar defects, block bone grafts from the symphysis and ramus buccal shelf offer advantages over iliac crest grafts, including close proximity of donor and recipient sites, convenient surgical access, decreased donor site morbidity, and decreased cost. He concluded that overall morbidity of mandibular block autografts for alveolar ridge augmentation is minimal. Most complications are preventable, and those that occur can be handled predictably with minimal adverse effects to patients.5

Simon Z., Friedlich J stated that several graft materials available commercially may be effective for augmentation but cannot predictably induce the differentiation of bone forming cells.it has been speculated that using biologically active substances for bone regeneration is optimal.PRP plus bone grafting is expected to enhance and speed graft consolidation.6

Tomoki Oyama, MD,Soh Nishimoto, MD,Tomoe Tsugawa, MD and Fumiaki Shimizu, MD§ used PRP along with autogenous graft in alveolar clefts & stated that PRP was a safe and cost-effective source for growth factors and was easy to extract. It could enhance the osteogenesis of alveolar bone grafting in cleft lip and palate patients and may useful for subsequent orthodontic therapy.4

Robert E. Marx, DDS, a Eric R. Carlson, DMD, b Ralph M. Eichstaedt, DDS stated that Platelet-rich plasma is an autologous source of platelet-derived growth factor and transforming growth factor beta that is obtained by sequestering and concentrating platelets by gradient density centrifugation. This technique produced a concentration of human platelets of 338% and identified platelet-derived growth factor and transforming growth factor beta within them.1

Tiossi, r.; mello; lopes, r.; di mateo m. & iyomasa, stated that a recent innovation in dentistry is the preparation and use of platelet-rich plasma (PRP), a concentrated suspension of the growth factors found in platelets. PRP is involved in wound healing and are postulated as promoters of tissue regeneration.7

6.3 AIM

The present study is done to evaluate clinical & radiological efficacy of mandibular symphysis

autogenous onlay graft with platelet rich plasma in correction of bony defects in maxilla and/or mandible.

6.4 OBJECTIVES

·  To determine donor and receptor site morbidity.

·  To determine amount of vertical alveolar gain using coole’s method.3

·  To evaluate success of graft using Bergland Scale for occlusal level of graft.2

7.0 MATERIALS AND METHODS

Autogenous corticocancellous bone graft harvested from patient’s mandibular symphysis region intraorally.

Titanium screws of diameter 1.5 mm with lengths varying according to thickness of graft placed.

Platelet rich plasma obtained from 10-20 ml of patient blood.

7.1 SOURCE OF DATA:

Patients visiting the Krishnadevaraya college of Dental sciences & Hospital, Bangalore.

7.2 METHOD OF COLLECTING THE DATA

Sample size includes minimum of 10 patients.

This study will be conducted in patients who have class B or class C type of maxillary and/or mandibular

bone according to Misch classification of available bone.

In this study 10 patients will undergo alveolar bone grafting with symphysis graft along with platelet

rich plasma.

Patients will be examined clinically at 1 week, 3 month & 5 months after graft placement.

Radiographs to be taken preoperatively and 5 months post-operatively.

INCLUSION CRITERIA

·  Patients with type B or type C residual ridges according to Misch & Jody classification of available bone associated with less than 4 teeth in maxilla and/or mandible.

·  Systemically healthy patient

·  Patient willing to participate in the study

CLASSIFICATION OF AVAILABLE BONE ( MISCH & JODY)10

Type / Length / Width / Height
A / > 5mm / > 5mm / > 10-12 mm
B / > 5mm / 2.5 – 5.0 mm / > 10-12 mm
C / unfavourable / unfavourable / unfavourable
D / Basal bone loss / Severe atrophy / Flat maxilla pencil mandible
E / discontinuity / defect

EXCLUSION CRITERIA

1)  Chronic smokers

2)  Patient with inadequate donor site.

3)  Those with large bony defect requiring augmentation that spans more than 3 teeth.

4) Medically compromised patients.

7.3. Does the study require any investigations to be conducted on the patients or other humans

or animals? If so please describe briefly?

a.  Routine hematological investigations

( Hb%, BT, CT, TC ,DC, RBS, HIV, HBsAG )

b.  Preoperative & postoperative study models

c.  Photographs

d. Radiographs:

1.  IOPA

2.  Occlusal view

3.  Orthopantamogram

7.4 Has ethical clearance been obtained from your institution in case 7.3 is applicable

YES
