Is a temporary denture support necessary after exo and prior to implants?

Suggestion If possible place an implant and use Autologous c.g.f. protocol ..... some use curing material to secure and stabilize the implant for bone integration Autologous membrane is the magic for tissue healing and fibrin block matrix in situ of implant to speed_up bone formation.... Also you will note patient comfort & best recovery ......

If possible not having a prosthesis putting pressure over a healing grafted or non grafted site will lead to optimal healing. The movement of the temporary is hard on he tissue and causes trauma and pain. As far as mesial drift is concerned a good rule of thumb is placing the implant within a six month period should suffice, that allows another 4-6 months for osteointegration. Patient parameters, age,periodontal status,crowding and occlusion are also factors. One has to look at this as a surgical healing site first. Ideally placing an Essex,splint or provisional above the tissue with no contact gives protection of the tissue and optimal healing. Avoid flippers at all costs if you want an optimal result they cause damage, resorption and tissue loss. It is just biology.Good question many practioners miss this

CRS gave som good advice. This all depends on perio status, opposing occlusion etc.

It can happen specially in perio patients or young patients. Have you thought about making a rochette type bridge(maryland without any tooth structure removal), we usually do it in casted CrCo , resin opauqe coverage and pressed acrylic, its simple, cheap and works like a fpp cemented with glass ionomer. It also protects grafted areas from undue pressure and you can shape the pontics to improve papillae contours. If you are worried about retention then you can add in the distal areas, instead of a rochette end, an ortho type casted band. They ussually last 3/4 months with a single lutting and if you are worried about the acrllic changing colour you can veneer the pontics with composite and you are done. Hope you like the idea.

Patient specifics would be helpful to provide you with practical advice. How old is the patient? Is this post-ortho implant placement? What are the proposed sites for implants? How many teeth remain and in what areas, i.e. is the occlusion stable? If in the posterior, then as CRS advised, no prosthesis is preferred. If anterior, especial max laterals, post-ortho, then a fixed provisional is preferred. I typically bond a Pontic to the adjacent teeth w/o reinforcement. Please provide details so we can meaningfully contribute.
