There is generally no visible gap between the full mouth dental implant holder and the gums. If there is a gap between the full mouth dental implant bracket and the gums, it may be due to an error in the crown molding or gum recession during the use of the dental implant. 1. Errors in crown molding: full mouth dental implants need to be molded according to the individual’s oral status, if there are errors in the molding process, it is possible that the dental implant bracket and the gums do not fit together, resulting in a gap between the two. Therefore, when trying on a full mouth dental implant, make sure that there is no gap between the implant holder and the gums, and then use adhesive to fix the abutment and crown. 2. Gum recession: During the use of full-mouth dental implants, if the gums recede due to plaque, calculus and other reasons, it is easy to cause a gap between the dental implant bracket and the gums, which affects the normal use of dental implants, and it is necessary to go to the hospital in time for follow-up, and the dental implants need to be removed and re-molded if necessary. Under normal circumstances, there is no obvious gap between the full-mouth dental implant bracket and the gums, if there is a gap, you should go to the hospital in time for a review, a clear diagnosis, and carry out targeted treatment as soon as possible.
