I've had upper 2nd molar extraction last year. It was broken in 2017 but few pieces remained. I've got cbct scanning and according to report my bone length is only 7 mm not sufficient fr dental implant. Cyst benign tumors is also seen in scanning and adjacent teeth has caries that was filled by a dentist. I'm 5.3 and weight is just 43 kg (loss 4 kg in lockdown). I have vitamin d deficiency (6.05) and low vitamin b3, b9, k. I do also have indigestion problems and hookworm infection was detected in stool in 2015. A week ago I had impacted wisdom teeth extraction and during procedure I experience syncope attack. Doc has talked to me and advised not to go for implant as i'm not healthy and have vitamins deficiency, you'll need 4 mm bone grafting and as you're not healthy complications can come you got to suffer then. I don't wanna have dental bridges as it may damage adjacent teeth.
