Patient: Examination and laboratory tests: The x-rays taken at our local hospital were brought with her when she went to the doctor. Treatment: Girl, 14 weeks, images show that all four of her six-collar teeth have underdeveloped roots (or have been partially resorbed), the lower right six-collar tooth has been extracted at our local hospital and is now undergoing orthodontic treatment to pull the seventh tooth forward. At present, the lower left and upper right two gums have developed abscesses, but there is no pain yet. The doctor proposed the following opinions: 1. conservative treatment plan: treat the teeth that are already inflamed and see how they develop before treating them; 2. complete treatment plan: since the other three teeth are ultimately unpreservable, they can all be extracted and orthodontic treatment will be performed to relocate all the seventh forward. If we want to use the second plan, will the other three teeth be extracted together, or will they be extracted in stages and the one that is not inflamed will also be extracted? (Option 1) If the four No. 7 teeth can be successfully moved forward to replace the severely diseased No. 6 teeth, it is a good choice, but whether it is feasible and whether three or four teeth can be extracted, it needs the orthodontist’s judgment; (In addition, extraction can be done in stages or at the same time, mainly because of the child’s poor tolerance. The main reason is that the child’s tolerance is low and it is hard to remove too many teeth at one time. (As for the effect of orthodontics on other teeth, you can consult the orthodontist, as far as I know, there is no adverse effect.) As for conservative treatment, I have not seen the child’s teeth, so it is not easy to judge. In brief: if the root condition is good, root canal treatment can be carried out, (Option 2) waiting for adult (around 18 years old) veneer, i.e. three separate crowns; if the root condition is poor enough to be utilized, it can be temporarily preserved, and then extracted in adulthood, (Option 3) for crown restoration (i.e. two teeth next to each other with one tooth in the middle), which may require 9 teeth; in addition, (Option 4) the three extracted teeth can be restored by adult implants. Alternatively, (Option 4) the 3 extracted teeth can be restored with implants as an adult, so that only 3 dentures are needed. Of the above options, option 1 is ideal as it will ultimately require no veneers and no dentures in the mouth, but it is a longer period of time and requires more confirmation from the orthodontist as to the child’s suitability. In addition, you will need to accept the option of extractions and the long commute to Beijing for appointments. All other options will eventually require veneers. Option 2 is relatively the least costly of several options, but requires confirmation from the pediatric dentist or orthodontist that the roots can be retained, as well as confirmation from the prosthodontist that the remaining teeth can be veneered; In addition to options 1 and 2, if the roots cannot be retained, option 4 is also a good option, but requires confirmation from the implantologist about the timing of the extraction and the timing of the implant; Option 3 is more secure, but Option 3 is more secure, but at a greater cost, requiring the sacrifice of 2 adjacent teeth (i.e. 2*3 healthy teeth). This is probably the case, and the choice needs to be considered by all of you.
