Splinted Crown due to Narrow Space: Hygiene?

You have no option but to make a splinted crown. Those implants are way close to each other. You should have had one woder implant and just one crown ideally.

My observation and experience with this type of treatment leads me to the following questions and advice: 1. did your dentist place the implants? 2. how long have implants been in place? 3. I don't know the reasons, conditions or experience that led to this treatment so I am only offering what I have seen and attempted to do in my practice. 4. It is not unusual to see two small diameter implants placed to be restored using two fitted abutments and one cemented crown. This is usually on the lower first molars that I have seen. I have done the lower treatment as described and seen others come in who have had this done. Results are mixed as to which is better, one wider implant and wide crown or two small implants with splinted abutments and one crown ; or two implants and two small crowns. If clinical space is available then any of these options can be done and only time will tell if the right choice was made. 5. Hygiene is the issue if the crown(s) are placed successfully. That is not only up to you but up to the case director, your dentist/implant surgeon, who should be able to guide you to success of treatment. 6. I don't know the clinical conditions. The xray type is always distorted up to 20% since it is taken on a curve of the head. 7. At this point in time, in my practice, I feel one implant and one abutment and one crown is the most predictable for success. 8. My opinion is that even taking an accurate impression of the two implants may not be possible due to the emergence long axis of the two impression posts intersecting each other and not allowing seating and/or tightening of both posts and /or removing them accurately without distortion. Even with extreme impression post modification, it is sometimes impossible of getting both in an impression. That means one implant won't be used. Better to take both out, bone graft including sinus. place on wider implant followed by abutment and crown; about 12 month time. This is my experience and opinion only. Sincerely Dr. Smith

Bone resorption has multi-caused origin and even a perfect implant insertion can be ruined by wrong prosthetic treatment plan. Let's hope that your dentist knows better what is the best in your particular case.
