Tas įtvaras (ar įtaisas, pritaisymas ar kt. - kas medicinos srity dirba geriau gal žinos, kaip tiksliai pavadinti) neleidžia dančiui judėti esant kaulo netekimui (sumažėjimui) ir tokiu būdu stabdo dar didesnį kaulo netekimą; įtvėrimas, sutvirtinimas atliekamas įvairiais būdais.

"Tooth mobility from bone loss accelerates bone loss when the disease process is active. It makes healing more difficult and potentially causes pain. There are many ways to [splint] and stop mobility including [crown] and bridge, intracoronal and extracoronal [splinting] with wire, fiber meshes or just composite. Mobility of less than one millimeter requires minimal [splinting] and might be overcome by occlusial adjustment. Mobility of one millimeter to two millimeters is [splinted] with fiber reinforced composite as seen below. Mobility of more than 2 millimeters or teeth that require extensive restoration require [splinted crowns] and contraindicate fiber reinforced composite."
