Maxillary Sinus Lift Up: An Indirect Approach for Implant Placement in Posterior Maxilla

[Year:2012] [Month:May-August] [Volumn:3 ] [Number:2] [Pages:42] [Pages No:101-104]


ABSTRACT

The posterior maxilla presents several challenges to the implantologist. Implant dentistry has become an excellent treatment modality since its inception into the modern era of dentistry. When patients present with deficient alveolar ridges, it could jeopardize the application of implant dentistry. This problem is especially magnified in the posterior maxilla where ridge resorption and sinus pneumatization are often encountered. The procedure of choice to restore this anatomic deficiency is maxillary sinus floor lift up. The purpose of this case report is to bring forward such technique which prevents perforation of sinus lining during implant placement by doing the sinus lifting with indirect approach through alveolar crest. The indirect approach for sinus lift is less invasive and less complex and therefore a better alternative for such cases.

Keywords:Maxillary sinus floor lift up, Implant, Indirect approach, Posterior maxilla.

Alveolar Ridge Preservation with β-TCP Graft and Platelet-Rich Fibrin

[Year:2012] [Month:May-August] [Volumn:3 ] [Number:2] [Pages:42] [Pages No:96-100]


ABSTRACT

Guided bone regeneration (GBR) procedures, employing nonvital bone grafting materials and membranes, were developed to counteract the significant resorption of alveolar bone following tooth extraction. Alloplastic graft material, consisting of pure phase of β-tricalcium phosphate (β-TCP) in the preservation of ridge volume after tooth extraction and before dental implant placement, is a well-accepted procedure. The healing potential of platelet growth factors has generated interest in using plateletrich fibrin (PRF) in ridge preservation procedures. In the present case report, β-TCP bone graft was combined with PRF utilizing the principles of guided bone regeneration to build the damaged edentulous ridge to receive dental implant.

Keywords:Platelet rich fibrin, Guided bone regeneration, Socket preservation, Platelet growth factors.

Periimplantitis

[Year:2012] [Month:May-August] [Volumn:3 ] [Number:2] [Pages:42] [Pages No:71-76]


ABSTRACT

Periimplantitis is an inflammatory process that affects both the hard and soft tissues around a functional implant and results in marginal bone loss, which may eventually lead to loss of osseointegration. Bacterial infection is known to play a major role in the etiology of this disease although there remains some debate as to whether this is a host susceptibility related or implant surface phenomenon or both. Prevention of these infections is a major factor when treating patients with implants, particularly, if they present with a periodontal disease. This article presents the etiology, pathogenesis and treatment of periimplantitis that has been seen to yield favorable results.

Keywords:Microbiota, Periimplantitis, Peri-mucositis, Periodontitis, Lasers.

Rehabilitation of a Patient using a Twin-Stage Technique to achieve Balanced Occlusion in Implant-Supported Overdenture: A Clinical Report

[Year:2012] [Month:May-August] [Volumn:3 ] [Number:2] [Pages:42] [Pages No:92-95]


ABSTRACT

Ideal occlusion on an osseointegrated implant has not been investigated with 6° of freedom biomechanically. The current accepted tenet is to avoid horizontal forces on fixtures and for edentulous cases, a balanced articulation must be created. Hobo and Takayama proposed a twin stage procedure to develop disocclusion and anterior guidance more precisely and scientifically. They concluded that effective cusp angle is the most reliable among all the factors effecting occlusion. They proposed a two stage procedure to develop effective cusp angle of 25º in order to achieve balanced occlusion in complete denture prosthesis. This clinical report describes a step-by-step procedure involved in developing balanced occlusion using twin stage technique in implant supported overdenture.

Keywords:Implant-supported overdenture, Twin-stage procedure, Condition I, Balanced occlusion.

Immediate Load Fiber Reinforced Hybrid Implant Prosthetics

[Year:2012] [Month:May-August] [Volumn:3 ] [Number:2] [Pages:42] [Pages No:83-91]


ABSTRACT

Immediate loading of implants placed at time of implant placement requires both adequate insertion torque and rigidity of the provisional prosthesis to allow placement of a restoration during the healing phase. Screw-retained provisional prosthesis allows better stability during the healing phase than cemented prosthetics and prevents cement seal breakage that could transfer greater loads to individual fixtures during this critical phase. Various methods of increasing the rigidity of the provisional material have been utilized and reported in the literature. A case describing the use of a woven fiber reinforcement ribbon will illustrate how to use this material and the benefits over either metal wire reinforcement or utilization of a cast frame.

Keywords:Immediate load, Fiber reinforcement, Provisional implant prosthesis.

Objective Assessment of Implants Stability placed in Fresh Extraction Socket using Periotest Device

[Year:2012] [Month:May-August] [Volumn:3 ] [Number:2] [Pages:42] [Pages No:67-70]


ABSTRACT

Objective: To present our experience of using periotest (PT) device for measuring implant stability in immediate implants placed in fresh extraction sockets.

Materials and methods: We used a PT device to measure for 10 implants placed in 10 patients over a period of 18 months. All the implants were placed immediately after extraction. The minimum follow-up period was 6 months with PT readings taken at 4th, 5th and 6th months (stage I) and after restoration at 7th, 8th and 9th months.

Results: Negative values are generally considered good. This means the implant is well osseointegrated and can be loaded. The PT values for the maxillary tooth were lower than those for the mandibular tooth. A stable mandibular implant presents PT value readings between –2 and +2. A stable maxillary implant presents PT value reading between –4 and –2.

Conclusion:PT enables us to assess osseointegration noninvasively and objectively in any situation. PT helps us to optimize our decision whether or not an implant is ready for functional loading.

Tissue Stability following Soft-tissue Augmentation and Zirconia Prosthesis: A 6 Years Follow-up

[Year:2012] [Month:May-August] [Volumn:3 ] [Number:2] [Pages:42] [Pages No:77-82]


ABSTRACT

Background: ‘Reconstructive esthetic implant therapy’ is a term evolved in the ever-demanding age of oral implantology today. Maintaining the critical factor in this delicate balance of the gingival/pink esthetics is the periimplant papilla. Its presence being a major esthetic achievement and its loss leads to tremendous esthetic handicap known as ‘black hole disease’. This case report addresses this fascinating yet challenging aspect of reconstruction of periimplant papilla through a novel technique.

Methods: A 38-year-old patient presented for replacement of missing tooth. Complete oral and periodontal examination, orthodontic intervention to prepare the implant site was undertaken. Preoperative soft-tissue assessments were done. A modified palatal roll technique was performed for reconstruction of the papillary architecture. Zirconia prosthesis was fabricated and the pink esthetic score (PES) around the prosthesis was calculated.

Results: An appreciable PES score around the prosthesis complete fill of the interproximal papilla and buccal soft tissue augmentation resulted from this technique.

Keywords: Papilla reconstruction, Palatal roll technique, Maxillary anterior esthetics.

Attitude toward Desire for Implant Treatment in South Coastal Karnataka Population: A Short-term Epidemiological Survey

[Year:2012] [Month:May-August] [Volumn:3 ] [Number:2] [Pages:42] [Pages No:63-66]


ABSTRACT

The purpose of this survey was to determine the awareness of dental implant as a treatment modality among the people of South Coastal Karnataka and their attitude and desire for implant treatment and also the various constraints in implant treatment.

Materials and methods: This was a questionnaire-based study carried out on 100 edentulous or partially edentulous subjects.

Results: The results were evaluated by Pearson Chi-square test.

Conclusion: It was seen that a large percentage of people were not aware of dental implant treatment. But when educated about it, they showed positive response toward it. Hence, ignorance remains the barrier between the need and utilization of advanced dental treatment modalities.

Keywords: Dental implant treatment, Attitude, Awareness, South coastal Karnataka population.

Cone Beam Computed Tomography and The Implant Receptor Site

[Year:2012] [Month:May-August] [Volumn:3 ] [Number:2] [Pages:42] [Pages No:v-vi]


ABSTRACT

CONE BEAM COMPUTED TOMOGRAPHY AND THE IMPLANT RECEPTOR SITE

During the past 30 years, the dental implant industry has matured. No longer thought of as ‘experimental’ dental implants are now the primary treatment alternative for patients who are missing teeth. It is understood that in order to place an implant, sufficient bone quality is required for initial stability and long-term function. Conventional two-dimensional imaging technologies do not provide clinicians with enough information to assess the cortical plate thickness, intermedullary bone, density or the spatial relationship to adjacent vital structures. Starting in the late 1980s, computed tomography (CT) came on the scene for dental applications and for the first time clinicians were given the opportunity to view their individual patient anatomy in three-dimensions. Interactive treatment planning software applications followed empowering clinicians with new software tools to navigate through the maxillofacial complex with a variety of different views. Specic tools were developed to understand bone quality and identify potential implant receptor sites and proximity to vital structures. Technology then linked the virtual plan to precision placement of implants with many competing CT-derived surgical guide solutions. The evolution of ‘guided surgery’ continues with dental implant manufacturers offering solutions and state of the art components that address accurate drilling, depth control and controlled delivery of the implant. There is, however, one important caveat:
‘The concept of ‘guided surgery’ may be flawed in one respect. A lack of agreement on where to place and implant within the receptor site.’1
