A Simple and Effective Technique to Fabricate Diagnostic and Surgical Stent

[Year:2010] [Month:September-December] [Volumn:1 ] [Number:3] [Pages:52] [Pages No:173-175]

Prosthodontic rehabilitation of completely edentulous arch with implant supported prosthesis requires a stent, to evaluate the relationship between anatomical structures and to aid in implant placement for successful treatment result. The lengthy treatment procedure where the clinician has to duplicate the existing denture for stent fabrication has created a need for an improved simple and time saving technique. This article thus describes fabrication of a surgical stent with acceptable retention, stability and teeth arrangement using simple and time saving lab procedures.
Keywords: Complete denture, Surgical stent, Implant.

Diagnostic Imaging in Implant Dentistry

[Year:2010] [Month:September-December] [Volumn:1 ] [Number:3] [Pages:52] [Pages No:147-153]

Dental implants have revolutionized the field of dentistry. Its immense popularity and wide acceptance has led to a point, where it has become a part of routine treatment plan in oral rehabilitation. For the success of implants, a presurgical treatment planning is of utmost importance. To aid this, diagnostic imaging plays a vital role. There are various modalities of imaging which will aid in placing the implant in an appropriate location with relative ease and also get a predictable outcome. This article focuses on the various imaging modalities available currently and their clinical applications. Modalities described are intraoral radiography, cephalometric radiography, panoramic radiography, conventional tomography, computed tomography, cone-beam CT and magnetic resonance imaging. The final selection of one these imaging modalities are dependent on the operator choice based on the patients need.
Keywords: Diagnostic imaging, Magnetic resonance imaging, Cone-beam CT, Dentascan.

CAD/CAM Implant Suprastructures: Accuracy, Durability and Precision

[Year:2010] [Month:September-December] [Volumn:1 ] [Number:3] [Pages:52] [Pages No:137-139]

Traditional methods for implant prosthetic frame fabrication have been complicated by the process utilized to construct the frameworks. The casting method has been shown to complicate passive fit to the implant fixtures due to shrinkage and expansion of the materials used to construct the prosthesis. Additionally, castings not providing homogeneous masses of metal and microbubbles in the cast metal are very common leading to potential weak points in the prosthesis. In recent years, technology has allowed CAD/CAM processes to virtually create these frames eliminating the expansion and contraction seen in castings. As these structures are milled from solid blocks of homogenous metal, bubbles are eliminated from the final prosthesis thus providing stronger frameworks. This article will discuss the pitfalls of traditional methods and the benefits of CAD/CAM implant fixed and bar-overdenture prosthetics.

Immediate Loaded Implant Supported Prosthesis with SynCone

[Year:2010] [Month:September-December] [Volumn:1 ] [Number:3] [Pages:52] [Pages No:169-172]

The rehabilitation of the edentulous mandible by means of implant-supported overdentures is well-established and documented. The majority of systems that adopt this approach, however, require a high level of laboratory support. While esthetics and function are considered the primary benefit of the dental implant procedure, patients also desire reduced treatment times.
A case is presented describing the immediate loading of 4 interforaminally placed implants with the use of prefabricated telescopic copings that may be incorporated in the patients existing denture chairside to significantly reduce the dependence on complex laboratory procedures.
Keywords: Immediate loading, Implant overdenture, Edentulous mandible.

Evaluation of Bioactive Glass as a Bone Graft Extender in Sinus Elevation Surgeries

[Year:2010] [Month:September-December] [Volumn:1 ] [Number:3] [Pages:52] [Pages No:155-162]

This study evaluated histologically and radiographically sinus elevation surgeries using PerioGlas (PG) in combination with autogenous bone (AB) or freeze dried bone (FDB).
Methods: Thirty-two elevations were done in 27 patients with five patients receiving bilateral elevation. PerioGlas was mixed with AB or FDB in a 1:1 ratio. All sinus elevation and implant surgeries healed uneventfully. Histologic samples were obtained as part of the subsequent implant placement procedure. A total of 37 Bio-Lok implants, 10-13 mm in length were implanted.
Results: All implants osseointegrated and successfully restored. Average bone gain at 6 months was 5.6 mm for PG + AB and 7.4 mm for PG + FDB with no clinically significant difference between either. PerioGlas, in addition to its osseous regenerative properties, displays excellent handling characteristics and with its osteostimulatory properties, can be used as a bone graft extender for sinus elevation surgeries.

Change in Paradigm: Dental Implant Loading

[Year:2010] [Month:September-December] [Volumn:1 ] [Number:3] [Pages:52] [Pages No:141-145]

Restoration with dental implants has proven to be a predictable modality for replacing, missing or failing teeth with various types of fixed or removable dental prostheses. Loading protocols for dental implants have been a central focus of discussion in the field since the origin of osseointegration. Several consensus conferences have been held on the topic, and recommendations have been published based on the evidence available at the time. This is a systematic review of change in treatment modality which has taken place from the delayed loading to immediate loading. The source of literature was Pubmed database.
Keywords: Dental implant, Loading, Prosthesis.

A Comparative Evaluation of Outcome of Endosseous Implants placed in Fresh Extraction Sockets with and without use of Plasma Rich in Growth Factors (PRGF)

[Year:2010] [Month:September-December] [Volumn:1 ] [Number:3] [Pages:52] [Pages No:123-135]

Introduction: With the ever increasing success rate of dental implants, researchers and clinicians have turned their minds towards making the duration of treatment shorter and more comfortable. Many studies have been conducted using various graft materials in conjunction with implants for initial stability in immediate placement.
Materials and Methods: In this study, we have included the patients from our local area Delhi NCR and 20 implants were used, out of which 10 were wetted and covered with PRGF and remaining were placed without any similar adjunct. The patients were prospectively evaluated for implant stability clinically, radiographically and using radiofrequency devices.
Results: It was observed that patients in the PRGF group reported lesser pain and swelling at the site of implantation. The soft tissue healing in PRGF group was exemplary in experimental group. In the experimental group the stability values showed an early recovery from the remodeling phase between 2nd and 4th weeks postoperatively. In our study, stability values after 12 to 24 weeks were approximately same for both the groups.
Conclusion: As an outcome of this study, we can recommend PRGF as an adjunct with implants, placed in fresh extraction sockets, as it may improve the success rate and decrease the treatment duration.
Keywords: Immediate implants, Plasma rich in growth factors (PRGF), Resonance frequency analysis (RFA), Osstell.

Management of Failed Implant Site with Symphyseal Graft in Combination with Xenograft and 4-year Follow-up Post-reimplantation

[Year:2010] [Month:September-December] [Volumn:1 ] [Number:3] [Pages:52] [Pages No:163-167]

Implant failure results in a considerable bony defect, often requiring multistaged treatment for achieving optimal hard and soft tissue volumes prior to reimplantation. Fresh autogenous cancellous bone is ideal for secondary alveolar cleft bone grafting, for such defects, because it supplies living, immunocompatible bony cells that integrate fully with the maxilla and are essential for osteogenesis. When combined with a slowly resorbing particulate graft like a xenograft, a stable platform for implant placement can be expected.
Keywords: Implant failure, Symphyseal graft, Xenograft.
