Cosmetic partials are light and durable. They are mostly metal free and comfortable. The best feature about these partials is that they are not as harsh or detrimental to existing teeth as the conventional partials. Conventional partials depend on surrounding teeth as anchorage with metal clasp and hooks that grab on to adjacent teeth.
After a few years, conventional partials could loosen teeth that metal clasps are hooked on which may force some teeth to be extracted.
