Thank you for your question. I'll do my best to answer it for you.There are different type of dental appliances and technique for each case in dentistry and prosthodontics.When I have a patient with the periodontal disease most of the time I use telescopic denture or crown for the treatment. because it prevents bone loss,improves chewing efficiency and gives a proper jaw alignment.Periodontal disease causes the gingiva to recede, loosening teeth,and leading to loss of teeth one by one.Telescopic technique (crown , denture)restore new teeth for periodontal patients.Telescopic technique ensures that bite stress is distributed evenly between each tooth(if we use normal crown each tooth has its own chewing efficiency according to size)and protecting the remaining teeth and periodontal tissues and the end result look quite natural and can last a lifetime and increase chewing power.Finally As a dennist specialized in prosthodontics, I prefer telescopic crown for the patient with periodontal disease and your dentist's choice was correct.If you have any more questions, I am happy to help as much as possible so feel free to ask.
Thanks for your reply and advise. I understand that this technique is not used in the US, if at some point the appliance needs repair or there is more tooth loss for any reason can the repair be made in the USA in the event of tooth loss can adjustments be made to the devise here in the USA?
And one more thing... how comfortable is the telescopic denture/ crown when used on the lower jaw?
