Pedo vs Materials — Key differences for NEET MDS
Band and loop = unilateral posterior premature loss. Lingual arch = bilateral mandibular space maintenance. Nance button = bilateral maxillary space maintenance. Distal shoe = second primary molar lost before first permanent molar erupts. Transpalatal arch = maxillary anchorage. Leeway space = E space difference primary second molar and premolar. Mandible leeway = 1.7mm per side.

Polysulfide = longest setting time messiest = lead dioxide accelerator. Polyether = stiffest most hydrophilic = initial rigidity. Alginate = irreversible hydrocolloid = snap set. Agar = reversible hydrocolloid = high detail low strength. Impression plaster = most rigid.
