Mandibular Nerve block (Other techniques).ppt

Long Buccal Nerve Block,Anterior branch of Mandibular nerve(V3)Provides buccal soft tissue anesthesia adjacent to mandibular molarsNot required for most restorative procedures,Buccal Nerve Block,Indications Anesthesia required-mucoperiosteum buccal to mandibular molarsContraindications Infection/inflammation at injection site,Buccal Nerve Block,Advantages Technically easy High success rateDisadvantages Discomfort,Buccal Nerve Block,Alternatives Buccal infiltration Gow-Gates PDL Intraseptal,Buccal Nerve Block,Technique Apply topical Insertion distil and buccal to last molar Target-Long Buccal nerve as it passes anterior border of ramus Insert approx.2 mm,aspirate Inject 0.3 ml of solution,slowly-25-27 gauge needleArea of insertion:-Mucosa adjacent to most distal,Buccal Nerve Block,Landmarks Mandibular molars Mucobuccal fold,Buccal Nerve Block,Complications Hematoma(unusual)Positive aspiration 0.7%,Mental Nerve Block,Terminal branch of IAN as it exits mental foramenProvides sensory innervation to buccal soft tissue anterior to mental foramen,lip and chin,Mental Nerve Block,Indication Need for anesthesia in innervated areaContraindication Infection/inflammation at injection site,Mental Nerve Block,Advantages Easy,high success rate Usually atraumaticDisadvantage Hematoma,Mental Nerve Block,Alternatives Local infiltration PDL Intraseptal Inferior alveolar nerve block Gow Gates,Mental Nerve Block,Complications Few HematomaPositive aspiration 5.7%,Incisive Nerve Block,Terminal branch of IAN Originates in mental foramen and proceeds anteriorlyGood for bilateral anterior anesthesia Not effective for anterior lingual anesthesia,Incisive Nerve Block,Nerves anesthetized Incisive Mental,Incisive Nerve Block,Areas Anesthetized Mandibular labial mucous membranes Lower lip/skin of chin Incisor,cuspid and bicuspid teeth,Incisive Nerve Block,Indication Anesthesia of pulp or tissue required anterior to mental foramenContraindication Infection/inflammation at injection site,Incisive Nerve Block,Advantages High success rate Pulpal anesthesia w/o lingual anesthesiaDisadvantages Lack of lingual or midline anesthesia,Incisive Nerve Block,Complications HematomaPositive aspiration 5.7%,
