"Holding arch" is a clinical umbrella term for any fixed appliance that passively holds bilateral arch space after premature primary molar loss. In the upper arch this is typically a Nance holding arch (Nance holding arch); in the lower arch it is a lingual holding arch (Lingual holding arch / Lingual holding arch). The appliance has no active components — it simply prevents first permanent molars from drifting mesially into the space left by lost primary teeth, preserving room for erupting premolars.
Molar bands cemented to the first permanent molars connect to a wire framework running lingual to the arch. The wire contacts the anterior teeth (lower) or the palate (upper), providing a stop against mesial molar migration. Forces are passive and light — essentially preventing drift rather than generating active movement.
Bilateral premature loss of primary molars in either arch; Leeway space preservation in late mixed dentition to avoid crowding; holding space after extraction pending eruption of permanent successors; adjunct to comprehensive treatment planning when mixed-dentition space management is needed.
Passive only — cannot regain space already lost (use a space regainer Space regainer for that). Must be removed or replaced as permanent teeth erupt. Hygiene challenge — requires diligent flossing around the wire.
Lower: 0.036″ SS wire on lower first molar bands, running lingual to lower incisors. Upper: wire + Nance acrylic button on palate (see Nance holding arch). For full fabrication details, see Lingual holding arch (lower lingual holding arch) and Nance holding arch (Nance holding arch).
See Lingual holding arch for lower arch fabrication. See Nance holding arch / Nance button for upper arch fabrication. Both follow the same general principle: band-fit, wire adaptation, soldering, polishing.
