OBJECTIVES/GOALS: The objective of the study is to compare two horizontal bone augmentation techniques (bone expansion and bone splitting) that are currently used for horizontally deficient maxillary ridges. Bone expanded in millimeters (mm), implant stability, and patient satisfaction will be compared with each technique. METHODS/STUDY POPULATION: This pilot (prospective cohort) study will be divided in two sites, a private practice and the Oral and Maxillofacial Surgery (OMS) Clinic at the University of Puerto Rico, School of Dental Medicine. A total of 20 patients will be selected, 10 patients in each site. In both sites, pre-operative and post-operative Cone Beam CT radiographs will be taken to measure bone width. Implant stability will be measured using an Osstell. 2 weeks post-surgery, a patient satisfaction questionnaire will be given to patients. A two-sample T test will be used to compare techniques statistically. RESULTS/ANTICIPATED RESULTS: We anticipate that bone expansion will be as good as (non-inferiority) bone splitting in terms of bone expanded in millimeters to desire width, and implant diameter will not be compromised. We also expect that implants placed with the bone manipulation technique will have a higher implant stability at baseline and less pain, discomfort and swelling in terms of patient satisfaction. DISCUSSION/SIGNIFICANCE OF IMPACT: Our contributions here are expected to illustrate clinical and radiographic bone expansion techniques that will enhance implant placement treatment for implantologists and patient’s experience.

Additive manufacturing technology or 3-dimensional printing has been used since ages in various fields including medical. Their addition to dentistry is recent and has tried to revolutionize the field. It is being used in various fields of dentistry like endodontics, prosthodontics, orthodontics, oral and maxillofacial surgery and recently in periodontics and Implantology. With introduction of recent “layer-by-layer” additive technology, their use in periodontal field has changed its treatment planning. It is use in preparation of customized scaffold with or without stem cell therapy, ridge augmentation, sinus lift and guided implant surgery, implant fixtures, education models, drug technology and many more. This review has tried to explain the various applications of the additive manufacturing in the field of periodontics with recent evidences. This paper highlights the role of 3-dimensional printing which can change the future of periodontal management.

Dimensional Printing

The three-dimensional printing has been used since very long ago in the field of medicine as well as in dentistry. The evolution of 3-dimensional imaging and modelling in dentistry is progressing towards a more efficient and cost-effective workflow using state-of-the-art technology. The practicability of this technique is expanding in several dental fields such as prosthodontics, oral and maxillofacial surgery and prosthesis, and production of surgical guides or physical models in dental implant treatment. The key of success in this technique depends on the usage of various materials such as, metal, resin, plastic etc. which is most commonly used in dentistry. With introduction of this recent advanced technology, it is used in various surgical procedures such as ridge augmentation, sinus lift and guided implant surgery, implant fixtures, preparation of customized scaffold with or without stem cell therapy, education models as well as in drug delivery technology. The 3-dimensional printing technology is becoming more economical technique and able to produce replica of dental models with a high resolution and accuracy.

Autologous Platelet Concentrate

Platelet Rich Fibrin (PRF) is autologous biomaterial which is the second-generation platelet concentrate. It has a favorable biological properties that accelerate healing of soft tissue, and bone, giveing a wide range of applications found in oral and maxillofacial surgery and other surgical fields. PRF technique was developed by Choukroun et al in 2001 and it represents a second generation of autologous platelet concentrate, which is used to accelerate the healing of soft and hard tissue. In contrast to the PRP, the PRF is composed of autologous fibrin matrix in which a large amount of platelets and their growth factors are embedded. PRF-graft is used in augmentative techniques residual bone defects, alone or in combination with biomaterials. When the alveolar ridge augmentation technique GBR, the PRF membranes can be used for protection and stabilization of bone compensation. PRF accelerates the healing of soft tissue and reduces the possibility of dehiscence and exposure of the membrane.

Angle Fracture

Background: Mandibular fracture is the most common facial bone fracture. Fractures occurring at the Para symphysis region frequently results in mental nerve injury, due to which anaesthesia or paraesthesia of the skin and mucous membrane within the distribution of mental nerve may be observed and may cause reduced quality of life for patients. Aim of this study was to retrospectively analyse and evaluate the prevalence rate of mental nerve injury in patients that reported to the department of oral and maxillofacial surgery, managed conservatively or open reduction and internal fixation method during the last 3 yearsMethods: Patients with neurosensory deficit following para symphysis fracture were recorded, statistically analyzed and results and observation were prepared from it.Results: The patients with age group 21-30 diagnosed with para symphysis fracture constituted 25% of all operated case and were found to be more associated with midface and angle fracture. Etiology behind the trauma was mostly as a result of RTA. Neurosensory disturbances as a result of mental nerve injury were found to be associated in 20.89% case, out of which in most of the cases, it gradually recovered within a duration of 7-15 days.Conclusions: RTA’s have been a prime cause for para symphysis fracture, which may at times accompany neurosensory deficit following trauma or may occur post-surgery, has been found to cause troublesome sequelae and reduced quality of life. Moreover, further research study needs to be carried out over a larger time span having a larger group of patients.

AbstractAnalysis of pre- and postoperative casts is essential in evaluating the efficacy of hydroxylapatite implant procedures for denture support. Computergraphics have been used to quantitate the changes in anatomic contour of occlusal surfaces of teeth and in the diagnosis and treatment of patients with craniofacial malformations. They may prove to be a useful adjunct in the planning and execution of preprosthetic oral and maxillofacial surgery for ridge augmentation. Thus computergraphics may be useful in surveying pre- and postaugmentation casts and evaluating clinical outcomes. In addition, computergraphics may also be useful in evaluating the utility of various surgical techniques used to augment ridges. In this study, pre- and postsurgical maxillary and mandibular casts were made from tissue displacing, irreversible hydrocolloid impressions. A comparison of pre- and postsurgical ridge contours, surface areas and volumes were derived from computer digitized two-dimensional tracing of casts sectioned in the frontal plane. This was accomplished using a three-dimensional computergraphics program that reconstructed digitized two-dimensional images into a three-dimensional image which displayed ridge contours, surface areas and volumes. The application of computergraphic technology may also prove useful in quantitating and mapping time-dependent morphological changes in ridges supporting the prostheses. Thus this technique may be useful in monitoring resorption patterns in underlying bone as well as in the revision and compaction of implanted materials.
