A Case Series of Neutral Zone Recording in Prosthetic Rehabilitation of Mandibular Residual Ridge Height Defect

Background: The neutral zone recording is commonlyutilized in severely resorbed ridges that posechallenges to prosthetic retention and stability due toa lack of alveolar ridge height and width. Prostheticrehabilitation of mandibular defects that lack residualridge height is equally challenging and requires carefulplanning and fabrication of prosthesis that will bestable, retentive, and functional.Objective: To utilize neutral zone recordingsimpression in construction of prosthesis for therehabilitation cases with mandibular residual ridgedefects and evaluate outcomesCase Series: This case series involved four femalepatients aged 52, 28. 26 and 26 years respectively, whocomplained of poor appearance, inability to masticateand speak effectively, and requested prostheticrehabilitation following a surgical treatment forameloblastoma. All the cases were reconstructed afterthe surgical intervention without any form ofprosthesis. Case 1 had a segmental mandibularresection; case 2 had partial mandibulectomy; case 3had a subtotal mandibulectomy and alveolar bonegrafting while case 4 had subtotal mandibulectomy.Conclusion: The use of neutral zone recordingimpressions in plate reconstructed mandibulardefects, improved prosthesis retention and stabilityand gave a satisfactory outcome
