I have several teeth that have previously had root canal treatment, and I have been told that some of them may have infections around the roots.
Which teeth may need to be extracted, can implants be placed in the same areas, and what would my overall restorative treatment plan look like?

ANSWER
Based on the initial assessment, several areas require careful evaluation because some teeth have previous root canal treatment and signs of infection.
Teeth 13, 15, and 17 are planned for extraction and replacement with dental implants.
Before placing an implant in the tooth 17 region, a three-dimensional CBCT scan will be required because tooth 18 is impacted. Its position in relation to the planned implant site must be assessed carefully before surgery.
For the upper right side, 5 zirconia restorations may be planned in the region from teeth 13 to 17, depending on the final implant positions and the condition of the remaining teeth.
Proposed Treatment Plan
Extraction of teeth 13, 15, and 17
Dental implants in the regions of teeth 13, 15, and 17
CBCT evaluation of the impacted tooth 18 before implant placement in the tooth 17 region
5 zirconia restorations from teeth 13 to 17
In addition, teeth 33, 34, 43, and 44 have previously undergone root canal treatment and currently show signs of infection around the roots.
These teeth will need to be evaluated individually. Depending on the severity of the infection and the amount of healthy tooth structure remaining, treatment may include:
Repeat root canal treatment to preserve the tooth, if possible, or
Extraction followed by dental implant placement if the tooth cannot be predictably saved
The final number of extractions and implants may therefore change after clinical examination and CBCT evaluation.
This should be considered a provisional treatment plan, as the prognosis of the previously root canal-treated teeth must be confirmed before the final restorative plan is completed.
