Consequences of not replacing missing tooth
Definition: Any dental prosthesis that is luted, screwed or mechanically attached or otherwise securely retained to natural teeth, tooth roots, and/or dental implant abutments that furnish the primary support for the dental prosthesis. This may include replacement of one to sixteen teeth in each dental arch. (GPT 8 -2005)
Indications � Short span � Sound teeth � Ridge resorption � Patients preference � Mentally compromised � Physically handicapped
Contraindications Large amount of bone loss � Very young patients � Periodontally compromised abutments � Long span � Bilateral span � Congenitally malformed teeth � Mentally sensitive patients � Very old � Medically compromised �
Diagnosis � History � Diabetes: ○ High risk of periodontal diseases therefore increase chances of abutment failure � Xerostomia ○ High risk of caries (Fluoridation is advisable) � Cardiovascular diseases ○ Electrosurgical procedures are contraindicated ○ Adrenaline is avoided in LA & retraction cord � E/O Examination � TMJ � I/O Examination
� Diagnostic casts �Dimensions of edentulous spaces �Height, rotation & inclination of abutment teeth's �Presence of any wear facets (attrition) � Radiographic examination � Caries � Level of alveolar bone � Crown-root ratio of abutment teeth � Morphology of roots of abutment teeth � Quality of endodontinc restorations � Width of periodontal ligament space
Treatment Planning � Resin bonded FDP � Defect free abutments � Single missing anterior tooth/premolar � Young patients � Abutments with less than 150 axial inclination � Absence of deep bite � Conventional tooth supported FDP � Periodontally sound teeth � Short span � Absence of any uncorrectable soft tissue defect � Presence of proper salivation � Implant supported FDP � Long span � Free end saddle � High caries risk patient � Young adults
