Examples of Dental Work Carried Out By Dr Zielinski. Each Case is Unique & Results Will Vary Depending On The Individual
Lower overdenture case study in adelaide
History
66 year old fully edentulous male
Lost teeth due to periodontitis over a long period of time, severely resorbed lower ridge
Had a full lower denture(FL), not very happy with it
Remaining upper teeth extracted about 3 years ago
Chief concern “wants to be able to chew and stabilize dentures“
Made him new FU/FL dentures which are not retentive as ridge severely resorbed.
Can function in new dentures but the lower moves and top drops down anteriorly
Patient not concerned about aesthetics just speech and function
Diagnosis and Plan
Place two lower implants(Nobel Active 4.3x13mm) with Locator abutments to stabilize lower denture
Medically compromised patient with difficult access. Single stage surgery under GA
Load implants after 2 months.
Procedure
Constructed well fitting FU FL dentures
After 1 month denture function and bite balancing, copied dentures to make up clear acrylic FU FL
Placed radiographic markers on the lingual of canine sites and obtained a Cone Beam Volumetric Tomogram(CBVT).
Drilled 2mm pilot drill holes in the guide adjusted accordingly from the markers on the CBVT
Result
Fit Locator abutments
Remake FU/FL reset teeth lingually as patient has had 10 months of new dentures and should be able to cope with teeth set back
Fit locators to FL chairside with GC Unifast resin
