Actually what would be very helpful would be a clinical photo since oral cancer does not usually present in this manner. The lesions are exophytic and bone destruction is a later finding or a metastatic process. Oral cancer does spread locally and can invade bone. But all this is conjecture until a tissue diagnosis is made. This patient would get better care in the hands of a skilled OMS who can manage pathology, sinus invasion, and other complications from the surgery. And I might add primary closure. I stated the locators since thus patient needs to be able to handle simple hygiene first, and it is a very simple concept to place four parallel drawing locators for a tissue borne implant retained prosthesis, it works quite well. Yes I said it a prudent dentist would refer this to an OMS and put the patient welfare first. I have had much experience with general dentists, periodontists etc treating these cases and having to treat the problems or sequela afterwards, whatever rationale given, time, convenience, costs are just that rationale to justify taking on a case for whatever reason. Some of the posts on this blog show how little knowledge,skill and experience is prevalent in oral and maxillofacial surgery. This can't be obtained in a weekend course or a fancy gadget. I respect what my dental colleagues can do in their fields and work with them as colleagues. I don't tell them how to restore they should know that. Actually complications and poor treatment of these cases will drive to patient away with a poor experience for the patient. I 'm very sorry if I offend dentists but sometime an honest opinion is better than trying to make a referring dentist feel better. My concern is for the patient who has been entrusted to us. General dentistry, implantology, perio etc are difficult enough when done well not to mention Oral Surgery where the buck usually stops. There are many practitioners who wisely get this, and there are those who have sleepless nights. I only share what I have seen and post because I do care no one is perfect myself included. Thank you for reading I know I will get criticized for this but I feel that it was necessary to address the elephant in the living room.

Wow! this IS a conversation we in dentistry need to have-
first let me say that if you look at the individual images vs the pan they don't appear to be from the same picture and if you are saying that the cloudy nature of the lesion on the left side of the side slice is disconcerting what about the cloudy nature above the bicuspids on the right slice . I think this is about the conebeam reformatting and these are not diagnostic or a true radiographic assessment of the areas.
second I don't think any Gp is going to explore this region up tho the pts brain and keep going or do I think they would avoid referring this if the find an odd appearance after extraction of the teeth or tissue healing issues. All the problems the pt has that you mentioned will be the result of the extensive surgery to remove the lesion not because the GP took out the teeth and you are not going to be bailing out a dentist here you are going to be doing your job as part of a team.
So tell me ,as oral surgeons, I am still waiting for what your first step is here- Im a general dentist - educate me on why you dont take the teeth out first or do you? do you do your biopsy before the extractions, during, or after healing ?
How are you going to get primary closure here and why do you want it? When are you going to graft-are you going to graft into these infected sites and then attempt primary closure? Are you going to have a denture made for immediate insertion and if you are what is the dentist to do when you have pulled all of the tissue over for primary closure-- It is easy to discuss the procedures you are going to do but discuss the timing of this Are you going to extract and do the invasive resective surgery at the same appointment if you determine that the consistency of the tissue is odd or will you biopsy at this point and see what turns up? so if there is a funny tissue here will you continue to currette up into the sinus at this appointment before you know what you are dealing with? If it is cancer are they all treated the same or are some irradiated first or treated with chemo to decrease the size or do you just start removing tissue? What happens to the keratinized tissue when you do primary closure and now you send them to me to restore? I get primary closure with a resection but not with extractions that makes no sense to me
You've placed implants at the bicuspid and cuspid retained by locators Im not aware of any study that confirms this as a successful procedure in the maxilla. It may be easy to put the implants in, get them parallel and place locators surgically this is a win for you the OS but it is a disaster waiting to happen to the GP that has to restore this
-now the patient wants to know why the denture teeth break off or the denture breaks or the implants fail after a few years or the retainers are constantly replaced because the denture keeps getting loose Now the GP has to figure out what he is doing wrong because the implants integrated well,so it must be his fault - you as the OS are off the grid as far as the patient is concerned- the implant planning is all wrong but they integrated and the patient paid all that money and they expect it to work
for you the OS to think that this would work in this case shows a lack of knowledge of the dynamics of removable prosthetics, occlusion and occlusal dynamics--This is the elephant in the room- the GP has deferred to the surgeons the decisions about implant placement and the surgeon has given him the answer. The truth is that the success of the case is based on an understanding of the occlusal forces on the prosthesis and the lack of posterior support that is available here-yes this is more about denture dynamics than fixed prosthesis- Put an upper denture in here and you will soon see what the dynamics are going to be on your implants
It is easy to point out how you bail out the GPS and Periodontist for the things that show up in your office but Gps have been bailing out OS since implants were first placed It is the astute OS that learns the dynamics of the occlusion and treatment planning and the force dynamics that contribute to implant loss
What I see is that surgeons understand surgery, GP understand restorative but we don't know as a collective group the dynamics of the systems when combined with implants- you can't understand this in a weekend course-When was the last time your surgeon attended a course on implant treatment planning and occlusion
The more I learn about implants the more I see I don't know IMHO

Dr Bill my cases are treatment planned per the restorative doctor as it is restoratively driven surgery. My prostodontist likes four locators when appropriate in the maxilla, it is his call. Your questions were answered in my first post. I have attended many restorative courses but I still rely on my restorative colleague as he trusts me to perform the surgery per my judgement. I think you may be overthinking the process. I get very nice results I'm sorry that you have had such difficulties with your team. Funny but I treat you guys like the quarterback and I welcome the feedback, just hope you can hear my feedback. Perhaps the problem lies on the working relationships between team members. I know enough about occlusion and prosthetics to get into trouble so I respect my restoring doctor as he respects what I do and trusts it. Thanks for the comments!
