026.Complete removable denture: Troubleshooting

DR. JABER HUSSAIN AKBAR
Faculty of Dentistry, Kuwait University,Kuwait

The objective of this seminar is to review the complications with complete removable dentures treatment. This seminar reviews the causes of the complications and how to avoid or treat them. By illustrating these complications, a dentist can have a better understanding of the patient's chief complaint and provides proper treatment.

Recent improvement of implantology driven by computers deeply changed our point of view to treat patients. Using a CT scan based planing system, the surgeon is able to select the optimal location for implant placement. The SimPlant® program allows implant planning in 2D and 3D. Precise osteotomy control is performed using stereolithographic surgical guides. The SAFE System^TM is a serial instrumentation allowing transfer of planned implant positions to the mouth. Accuracy is not only related to security in implant placement, but also to aesthetics, placing implants in their optimum position even in fresh extraction sites to preserve bone environment.

Accuracy in implant placement allows not to open flap with a precision up to 0.3 mm. Pain and swelling are reduced to nearly nothing using trans-mucosal approach. Since 2002, vertical control of implant placement opened the way to the Immediate Smile^TM protocol. In this protocol, the bridge is made before the surgery without taking an impression and placed in the mouth during the same appointment as the surgery. The unique part of this procedure comes from the fact that the temporary bridge is screw retained on the implants without been relined and without using fancy and expensive components.

In Computer driven implantology, accuracy allows using long trans-sinusal implants anchored in the zygoma or in the pterygoid bone, without opening sinusal lateral windows. Even in the presence of minimum volume of basal bone, anchorage is very stable and can be used to immediately load prostheses. When flap access in not required a surgical guide can be used with either mucosal or teeth support.

The SimPlant^TM program is used to analyze CT scan data and make an implant planning in 2D and 3D, SurgiGuides^TM and SAFE System^TM used to accurately place implants in the mouth and Immediate Smile^TM components to deliver a fixed restoration in the same appointment as implant placement.

Bonding procedures and materials are being refined in restorative dentistry with every passing day. Bonding FRC posts to restore endodontically treated teeth have phenomenally improved since it started in the early 1980's especially with the advent of non-metallic esthetic restorations. Today, bonded FRC claim to compete with other and older well-established restorative procedures with presumably better properties and longer life-span for the involved teeth. Emerging new technologies have also reached the outskirts of the endodontic procedure itself with the new bonded endodontic filling materials that allegedly possess superior properties as compared to the aging gold-standard: gutta-percha. How do these procedures and materials get along with the basic requirements of endodontology and restorative dentistry, how do their assertions measure up to scientific evidence, and what are really the prospect regarding these issues?

029.Direct posterior composite stratification using a "split-increment horizontal layering innovative technique

PROF. KHAMIS A. HASSAN
  College of Dentistry, King Saud University, Riyadh, Saudi Arabia

The use of composite resin restorations in posterior teeth has increased considerably in the past few years. Specific "esthetic" composite resins for posterior teeth, as well as new operative techniques, have been developed which expanded the range of restoration alternatives available for the dental practitioner. These techniques are aimed to overcome some of the clinical difficulties encountered with these materials.

This presentation will discuss the contemporary trends utilized to directly build­up posterior teeth with "esthetic" composite resins. In addition, an innovative newly introduced "Split-increment Horizontal Layering" method for restoring large occlusal cavities with composite resins will be presented and highlighted.

Amazingly high caries bilaterality (bilateral occurrence of dental caries) has recently been reported in both primary and permanent teeth of Saudi children. The purpose of this presentation is to discuss implications of this high bilateral occurrence pattern of dental caries in these children. The implications of high caries bilterality can be divided into three categories; clinical, preventive and public health implications. Presence of caries on one side of the mouth would warrant a careful clinical and radiographic examination to rule out presence of caries on the contralateral side. If the contralateral tooth is sound, additional preventive efforts would be required in the form of fissure sealants and topical fluoride applications. The phenomenon of caries bilaterality may also be utilized in dental public health e.g. in large caries surveys in future. It is hoped that with appropriate clinical and preventive practices, the high caries bilaterality in Saudi children can be exploited to our advantage, and to improve the management and prevention of dental caries in Saudi children.
