Sequelae of Denture earin!

1. Remember: the borders on the denture need to be roundeda. If you leave it thin it will be sharp like a razor blade

2. Residual Ridge Resorption

a. A physiologic process after teeth etractedi. !he bone"s reaction to the denture is to disappear

b. A variable process# dependent upon individual forcesi. It depends on that individual patient and that individual denture

ii. $ome people believe the process is inevitable and we can"t do anything about it

iii. %thers believe that we not only can slow it down but we can stop it# we &ust don"t know how yet'. %ne method for slowing down the residual ridge resorption

a. (e have discussed many methods to achieve this )probably 1* or 1+,i. %verdenture abutments

ii. -inimize the resorption using the $nowshoe rinciple / placing the denture on as much area aspossible

iii. %cclusion

iv. !ooth locationv. utting the teeth somewhere other than where they came from

vi. 0aving the anterior teeth out of contact

. %verdenturesa. !here are many options to affi the denture to the roots of the remaining teeth or to implants

i. ample: RA attachments or 3lei4overdentureb. If using implants you can cast a bar that will attach to all of them )typically ' or implants, and then the

denture will screw into that bar / I believe it is called a 0ater bar+. $e5uelae: -ucosal 6esions

a. !raumatic 7lcersb. Inflammatory apillary 0yperplasia

c. Angular 8heilitis )aka 9perleche,

d. ;enture $tomatitis< ;enture $ore -outhe. 3ibrous 0yperplasia. Inflammatory apillary 0yperplasia 9I0a. A reactive tissue growth usually developing under a denture

i. It is because the patient wears the denture both day and night

ii. !his is asymptomatic / so the patient does not feel itb. %ccurs on hard palate beneath denture base

i. ?ot on the soft palateii. If it has been there long enough it may migrate out to the crest of the ridge also )but it will start

up in the palate,

@. I0a. Asymptomatic red or pink nodules on mucosa of hard palate and occasionally the residual ridge

i. 9ebblyb. ;irectly related to constant wearing of ill4fitting denture and poor oral hygiene

c. 8andida fre5uently presenti. -any people believe that it is caused by 8andida

ii. %ther articles have shown that it is not caused by 8andida but that 8andida is present1. !he 8andida is there because the patient is constantly wearing the denture

. I0 !reatmenta. Remove denture at least @ hours

1=. pilus 3issuratum !reatmenta. $horten denture border

b. %ften re5uire surgical correctionc. Reline# rebase# or remake dentures

i. ou really need smooth and round bordersii. If it is too thin you will really have to shorten it to make it anything but sharp

1>. 8andida / a yeast4like fungus

a. A common oral microbeb. redisposing conditions: 0IC )immunocompromised,# diabetes# )elderly,
