Teeth are part of the body’s health, making up facial expressions and showcasing our health. Many people lose some or all of their teeth due to disease, accidents, congenital factors, or even impulsive tooth extractions. If you are missing a tooth or part of a tooth, there will be damage to your health as follows: (1) Tilting of neighboring teeth and deformation of the dentition – causing periodontal disease and facial changes. (2) Food is easily embedded – can cause tooth decay, pulpitis. (3) Elongation of the teeth on the opposite side – causes occlusion disorder and temporomandibular joint lesion. (4) Atrophy of the alveolar bone – the atrophy of the alveolar bone gradually increases, making it impossible to carry out traditional denture restoration. (5) Long-term lateralized chewing – causes unilateral muscle hypertrophy and asymmetric facial shape. (6) Affecting aesthetics and life – inability to speak and chew normally, and reduced digestive function.
