LLUSD - Chapter 5 - Diagnosis and Treatment Planning for Endosseous Root Form Implants The measurement error for linear tomograms has been determined to be about 2 millimeters.*TrueFalseMost of the postprosthetic implant losses occur during the first year after placement of the prosthesis.*TrueFalseImplants placed into Types I-III bone have a 4% failure rate whereas those placed into Type IV bone have a 16% failure rate.*TrueFalseImplant single crowns are associated with more complications than other types of implant prostheses.*TrueFalseThe Metabolic Equivalents (METS) Index uses 3 risk categories (major, intermediate, and low) that identify the highest level of activity that can be sustained without symptoms occurring.*TrueFalseA Class II jaw relationship may present challenges to the design of a fixed complete denture and an implant overdenture may become the treatment of choice.*TrueFalseOne of the limits of panoramic radiography is a magnification error that has been reported to be as high as 50%.*TrueFalseImplants that are longer than 10 millimeters in length have the same failure rate as those that are less than 10 millimeters in length.*TrueFalseNo significant racial or gender differences were found between the parallelism of the interpupillary line and a line drawn between the cusp tips of the right and left canines and the variation in parallelism was less than 1 degree.*TrueFalseProper phonetics may require the use of an implant fixed complete denture instead of an implant overdenture.*TrueFalseThe Minnesota Multiphasic Personality Inventory can easily be scored and evaluated by a dentist.*TrueFalseDuring smiling, the incisal edges of the maxillary anterior teeth should parallel the curvature of the superior border of the lower lip.*TrueFalsePatients were found to prefer smiles where the maxillary first molars were visible.*TrueFalseWhen developing a tentative treatment plan for completely edentulous patients, it has been determined that facial soft tissue support can be better with implant fixed complete dentures than with implant overdentures.*TrueFalseEight to ten millimeters is the minimum vertical space required between the edentulous ridge mucosa and the opposing teeth for placement of an implant fixed partial denture.*TrueFalseWhen placing an implant fixed complete denture, there should be at least 10 millimeters of anteroposterior distance between the most anterior implant and a line drawn between the two most posterior implants.*TrueFalseIt has been recommended that 17 millimeters of mesiodistal space be available when placing 2 implants.*TrueFalseWhen implant prostheses were placed in patients with schleroderma, there have been reports of difficulty with plaque control, impression making, prosthesis removal, and screwdriver access.*TrueFalseIncidence percentages have been identified in the dental literature for all the types of surgical complications that can occur in conjunction with implant palcement.*TrueFalseThe use of computed tomography permits the data to be analyzed in a computer. Bone height and width can be measured, an indication of bone quality can be made, and simulated implants of various diameters and lengths can be placed in the bone.*TrueFalseThe success of conventional prosthodontic treatment can be limited by resorbed edentulous ridges that are very tender when palpated and there is pain over the area of the mental foramen.*TrueFalseThe smoking cessation protocol that helped decrease implant loss included the complete cessation of smoking for 1 week before implant placement surgery and 8 weeks after surgery.*TrueFalseAn ASA II patient is a patient with moderate (to severe) controlled (treated) systemic disease or a patient who has multiple mild diseases.*TrueFalseRadiographic templates incorporate radiopaque material (objects) that locate the position of teeth on the resulting radiographs.*TrueFalseSmokers had an 11% implant failure rate versus 5% for non-smokers.*TrueFalseImplant dentistry should not be performed on ASA Status IV patients.*TrueFalseOral function improves when patients chew with implant supported prostheses.*TrueFalseIn the classification system of complete edentulism developed by the American College of Prosthodontists (ACP), Class III and Class IV patients are the ones most likely to benefit from implant therapy.*TrueFalseImplant loss is higher in the mandible than the maxilla.*TrueFalseClass IV edentulous patients (ACP classification) have a mandibular residual ridge height of 10 millimeters or less as measured on a panoramic radiograph at the area of the jaw that possesses the least vertical height.*TrueFalseWhen comparing facial esthetics from a profile view, all of the parameters evaluated (profile convexity, interlabial contour, nasolabial angle, mentolabial angle, and the relationship of the upper and lower lips to Rickettis E-plane) were found to exhibit significant differences between races.*TrueFalseOsteoporosis has been linked to an increased implant failure rate.*TrueFalseLinear tomograms and computed tomography are the most common types of advanced radiographs used in conjunction with implant dentistry*TrueFalseThe Levin and Landesman questionnaire begins with 3 questions that help determine if a complete denture patient is imaladaptive.*TrueFalseIn one study of ASA Class I, Class II, and Class III patients, the implant failure rate was found to be greater amongst the medically compromised patients.*TrueFalseClass IV edentulous patients (ACP classification) have a maxillary residual morphology that offers no resistance to horizontal and vertical movement of a complete denture.*TrueFalseInformed consent should encompass a description of the treatment, benefits, alternatives, risks, limitations, and the consequences of not performing the treatment.*TrueFalse
