Let me give you a professional answer ... To watch a movie, you must be at least 20 years old. The upper right 4 is missing, and all four 8' s exist, and none of them have retained value. It is recommended to remove them. The left inferior 8(38) is close to the mandibular nerve canal and needs to be removed by minimally invasive surgery. There is no need to plant top right 4 for the following reasons:

1. Because your teeth are prone to physiological mesial displacement, there is no gap between 3 and 5.

2. Low bone density, 4. If implanted, the osseointegration between implant (artificial root) and autogenous bone can not achieve good results. In general, the osseointegration rate should be around 70%, or at least 65%.

3. The periodontal condition of the upper right side is very poor, which is not suitable for planting. If you want to plant, you must do periodontal scaling. But in this case, this operation is not needed, just a supragingival scaling and subgingival scaling. Together, these two are what we often say: tooth cleaning, contact polishing after tooth cleaning, and then periodontal medication. Do not use iodine glycerin, use minocycline hydrochloride ointment, which is perio.

Finally, I am tired of typing so many words, hoping to get a good evaluation. I wish you the best of health!
