three implants or two implants and one tooth bridge

[barona]

My three teeth (R-H side upper jaw) 14,15,16 are missing.
My dentist advised they should be replaced by two implants and a one-to. He said that maybe I don't have enough width in my R-H upper haw.
I wanted three implants as I would lose bone under the bridge.
My oral surgeon says three implants are not necessary. I wonder why? I wasn't offered any explanation.
Then the two teeth 46,47 (R-H side Lower jaw) are to be extracted and replaced only by one implant.
although I wanted two implants.

Dental Implants that are required for the replacement of front teeth often vary in number, typically we do not need 3 implants to replace 3 missing teeth. Often there are space issues and placement of 3 implants can cause the implants to be too close to each other. This can make the new crowns and gums appear not natural. We often suggest placement of two implants in the lateral incisor positions and splinting a 3 unit bridge across. The lab technician can mimic the illusion of 3 teeth much easier with this setup. Goodluck !

Thank you ferberdental for your response.

1. I thought my teeth 14,15,16 are not front teeth as they are on the R-H side of my upper jaw.
So I would have an implant to replace nr 14, nr 15 would be a bridge and 16 an implant
instead of all 3 implants as per my request.

2. And as far as my R-H lower jaw is concerned the two teeth to be taken out are really big, so I thought placing
two implants would be ok?

The oral surgeon said there would be oral surgeons who would do what I want, but she thinks what she is doing is exactly what I need.

I think Ferber might not realise the notation system you're using, which is FDI. However, they are correct that only 2 implants would be required to replace the 14, 15, and 16.
For normal functioning, it is only necessary to have a single molar in each quadrant. Placing implants farther back for 2nd molars is more complicated because the bone gets thinner, and you are closer to major structures.

Thank you MattKW. Yes, I did use the numbering as per the attachment
I think both my dentist's and the oral surgeon's goal is to make my teeth functional as much as possible. I worry a lot about losing more bone and my face sagging (being vain, lol); so I was thinking, that even though an extra tooth won't be used for chewing, it would be preventing my jaw bone loss. However, thank you for explaining the way my specialists would reason.

So my maxillofacial surgeon is going to do the following:

Upper L-H side - a sinus lift + Implant (nr 26)
Upper R-H side - a sinus lift + 2 Implants (nr 14 & 16) with a space nr 15 left for a bridge
Lower R-H side - Two molars (nr 46&47) to extract and replaced with one implant nr 46.

Sounds good to me. Best of luck.
