In prosthodontic treatment plan, decisions must be made regarding oral tissue rehabilitation and other necessary pre-prosthetic measures. The rehabilitation prostheses are very useful devices in the field of prosthodontics. It is essential that the mouth should be in an optimal state of health prior to commencing prosthetic treatment and failure to achieve this may produce an unsatisfactory treatment result. Depending on a variety of situations, the dentist may find it necessary to modify the patient's existing dentures or, occasionally, to construct a special appliance. This article deals with several preliminary (non-definitive) treatment options available along with a brief account of their rationale.Keywords

Maxillomandibular defects may be the result of congenital malformations, trauma or surgical resection of tumors. The primary objective of rehabilitating these defects is to eliminate the disease by surgical resection and improve the quality of life for these individuals. Rehabilitating patients with maxillofacial defects is one of the most challenging therapies of the stomatognathic system.Prosthetic reconstruction of these defects may be achieved with the help of varied prosthesis, removable and fixed. The present case report describes a case of a large dentigerous cyst managed with a surgical obturator which allowed closure of the defect by secondary healing through granulation tissue maturation and associated bone fill. The obturator allowed decrease in size of defect and enhanced comfort and overall well-being of the patient till the complete filling of bone and till some permanent prosthesis is provided.Keywords

The science of Implantology has undergone numerous modifications and improvement and is highly dynamic. With each improvement and advancement, Implantology has proved to be a boon in disguise to the society and hence its acceptance by the general population has widely increased despite of expensive treatment modality. More of clinical trials conducted on different commercially available implants, its effect on bone and oral tissues as well as the development of implant designs, have increased the success rate of implants to over 95% and specially in anterior mandible where the success rate is over 99%. Latest technological advances in Dental Implantology are reviewed in this article.Keywords

New implant designs have appeared in the literature which claim that certain modifications may be helpful for maintaining crestal bone levels and consequently preserving normal soft tissue contours. Maintenance of soft tissue has been shown to depend on preservation of bone surrounding the implant. In order to achieve this goal, each step of the treatment must be managed carefully. This requires knowledge of pre-surgical treatment planning, site development, implant positioning, soft tissue management, provisionalization and prosthetic management.
Placement of a smaller diameter abutment on a large diameter implant platform (platform switching) has been proposed as an effective way to control circumferential bone loss around dental implants. The purpose of this paper is to evaluate the literature from an evidence based point of view regarding implant design modifications for preserving soft and hard tissue around implants.

Obstructive sleep apnea (OSA) is recognized as an important health issue in the last two to three decades. It is characterized by frequent episodes of upper airway collapse during sleep, causing recurrent arousals, intermittent hypoxaemia, sleep fragmentation and poor sleep quality. Obstructive sleep apnea (OSA) is a prevalent disorder with significant co-morbidities. There are evidences that OSA is being considered as an independent risk factor for hypertension, glucose intolerance/diabetes mellitus, cardiovascular diseases and stroke, leading to increased cardiometabolic morbidity and mortality. Early recognition and treatment of obstructive sleep apnea may prevent adverse health consequences. In this sense, treating the patient with obstructive sleep apnea requires a long-term partnership between patient and healthcare providers. With a strong partnership, obstructive sleep apnea may be effectively treated in the growing numbers of patients. In this article some of the epidemiological aspects, consequences, medical and dental treatment options of obstructive sleep apnea are reviewed.Keywords

An altered facial appearance is more difficult to face, than problems related to ill-fitting denture or eating. The selection of maxillary anterior teeth for complete denture has long posed problem in clinical practice and a controversy about the best method to employ still exists. An attempt is made in the present study to clinically correlate the face form with maxillary central incisor tooth form in males and females of Davangere population. In 1914, Leon William's projected the "the form method" where he classified facial forms as square, tapering, and ovoid. Maxillary central incisors were selected according to the facial forms.
Of total 100 subjects four different tooth forms and face forms were evaluated. They are: square, ovoid, square-tapered, tapered. No significant correlation existed between face form in male and females. Females exhibited greater correlation between face forms and inverted tooth form but that correlation is not sufficient to serve as a guide for selection of anterior teeth.

- Comparative Evaluation of Tensile Bond Strength of Nickel-Chromium Alloy to Dental Enamel Using Different Resin Cements-An in Vitro Study
Abstract Views :188 |
PDF Views:95
Materials and Methods: 40 extracted central incisor teeth embedded in acrylic blocks were flattened not to expose dentin.Wax rectangular blocks of 5mmlength, 5 mm width and 1 mm height with a loop were invested and casted using Nickel-Chromium alloy by conventional induction casting method and sandblasted. Then casted rectangular blocks and 40 tooth embedded acrylic samples were divided into four groups (10 each) and cemented to tooth enamel following manufacturer's instructions as; GroupAcemented using RelyX U200, Group B cemented using Smartcem 2, Group C cemented using Multilink Speed and Group D cemented using Multilink N and then stored in artificial saliva for 24 hours. The direct pull tensile test was carried out on Universal Testing Machine at cross head speed of 0.5mm/min.
Results: One way ANOVA showed a highly statistically significant (p<.01) difference between all the four resin cements. Post Hoc Tests- Multiple comparisons showed highly statistically significant (p<0.01) difference between RelyX U200: Multilink N, Smartcem 2: Multilink Speed, Smartcem 2: Multilink N, Multilink Speed: Multilink N. Difference between RelyX U200 : Smartcem 2 and RelyX U200 : Multilink Speed was statistically significant(p< 0.05).
Conclusion: Self etch resin cement (Multilink N) showed maximum mean tensile bond strength as compared to self-adhesive resin cements (Smartcem 2, RelyX U200 and Multilink Speed). Clinically the greatest advantage of self-adhesive cements is the easy and fast application technique. But this time saving technique is not as effective as selfetch resin luting agents. The presumed benefit of saving time with self-adhesive luting agents may only be realized at the expense of compromising bond strength.

When all the remaining natural teeth are removed, there exists a space within the oral cavity that can be called the potential denture space. Within this denture space there is an area that has been termed the neutral zone. Neutral zone is defined as that area or position within the oral cavity where the forces between the tongue and cheeks or lips are equal. Thus making it the zone of minimal conflict, where the function of musculature will not unseat the denture and help in stabilizing the denture. In the present case the neutral zone was recorded using admix technique and impression compound as the material of choice.Keywords

The Residual Ridge Resorption (RRR) is a major unsolved oral disease with unidentifiable characteristics and unwanted squealae causing physical, psychologic, and economic problems for millions of people all over the world. RRR is basically a term used to describe a condition that affects the alveolar ridge after tooth extractions even after healing of the wounds. RRR is a chronic, progressive, irreversible, and disabling disease, probably of multifactorial origin. The possible etiological factors could be divided into four categories: anatomic, metabolic, functional, and prosthetic. The primary structural change in the reduction of residual ridges is the loss of bone or reduction in the size of bony ridge under mucoperiosteum. The reduction in the ridge mainly occurs labially, lingually and on the crest. The reduction of the residual ridge leads to a variety of stages of ridge form, including high well-rounded, knife-edge, low well-rounded, and depressed forms.Alveolar bone atrophy is cumulative and irreversible, since alveolar bone cannot regenerate. It differs from one individual to the other. It also varies at different times and different sites. Some authors feel RRR as a normal physiologic process and not a disease but the cost in economic and human terms makes RRR as a major oral disease that can be described in terms of its pathology, pathophysiology, pathogenesis, epidemiology, etiology, treatment and prevention.Keywords
