1st visit 第一次就诊
Preliminary Impressions 初印模
Selection of stock tray. Modification of the tray with impression compound or autopolymerising acrylic as appropriate.
选择成品托盘。根据需要,用印模膏或自凝丙烯酸树脂对托盘进行修改。
选择成品托盘。根据需要,用印模膏或自凝丙烯酸树脂对托盘进行修改。
Normally a high viscosity alginate should be used as this will compensate for the lack of fit of the stock tray. A thin layer of adhesive should be applied to the tray before starting to mix the alginate.
通常应使用高粘度藻酸盐,因其能弥补成品托盘贴合度不足的问题。在开始调和藻酸盐前,需先在托盘上涂一层薄薄的粘接剂。

If surgical, conservative or periodontal treatment is indicated this must be completed before recording master impressions This is because the type of denture required may influence the overall treatment plan, e.g. rest seats incorporated into Class II restorations, full veneer crowns contoured to provide undercut areas for retention, or tooth extraction as a result of over eruption.
若需进行外科、保守或牙周治疗,则必须在制取主模型印模前完成。这是因为所需义齿的类型可能影响整体治疗计划,例如将支托凹整合到 II 类修复体中、全冠修整以提供倒凹区增强固位,或因过度萌出而需拔牙等情况。

2nd Visit 第二次就诊
Normally the second visit will be for master impressions if the preliminary casts have already been mounted and a design determined. In cases where the preliminary casts could not be mounted however, the second visit will be devoted to recording the jaw relationship of the patient prior to mounting casts on the articulator and developing a design.
通常情况下,第二次就诊将用于制取主模型印模,前提是初步模型已上架并确定了设计方案。然而,在初步模型无法上架的情况下,第二次就诊将专注于记录患者的颌位关系,之后再将模型上架到咬合架上并制定设计方案。

Recording Jaw Relationships
记录颌位关系
记录颌位关系
If an occlusal stop is present in the mouth you must determine whether the associated intercuspal position is acceptable. If there is horizontal (antero-posterior or lateral) deviation of the mandible after the initial occlusal contact, it may be necessary to correct the deflective occlusal contact by tooth modification, extraction or (rarely) orthodontic treatment. If there is loss of vertical dimension of occlusion (OVD) the appropriate increase will have to be determined by adjusting
如果口腔中存在咬合止点,必须判断其相关的牙尖交错位是否可接受。若初始咬合接触后下颌出现水平(前后或侧向)偏移,则可能需要通过牙齿修整、拔牙或(较少采用)正畸治疗来矫正偏斜的咬合接触。若存在咬合垂直高度(OVD)丧失,则需通过调整确定适当的增加量。

occlusal rims in relation to the rest vertical dimension (RVD).
与垂直距离休息位(RVD)相关的咬合堤。
与垂直距离休息位(RVD)相关的咬合堤。
For the purpose of jaw relationships and their registration partially dentate patients can be divided into two categories:-
就颌骨关系及其登记而言,部分缺牙患者可分为两类
就颌骨关系及其登记而言,部分缺牙患者可分为两类
· Patients without an occlusal stop to indicate the correct intercuspal position or vertical dimension of occlusion.
· 没有咬合止点以指示正确牙尖交错位或垂直咬合高度的患者。
· 没有咬合止点以指示正确牙尖交错位或垂直咬合高度的患者。
· Patients with occlusal contact in the intercuspal position.
· 在牙尖交错位有咬合接触的患者。
· 在牙尖交错位有咬合接触的患者。
First Category 第一类
In the first category the OVD is determined by establishing the RVD and modifying the occlusal rims until the OVD is some 2-4mm short of the RVD, this distance indicating the amount of interocclusal clearance. The horizontal jaw relationship recorded should be the retruded contact position.
在第一类情况下,通过确定相对垂直距离(RVD)并调整咬合堤直至咬合垂直距离(OVD)比 RVD 短约 2-4 毫米来确定 OVD,这一距离即为颌间间隙量。记录的水平颌位关系应为后退接触位。
在第一类情况下,通过确定相对垂直距离(RVD)并调整咬合堤直至咬合垂直距离(OVD)比 RVD 短约 2-4 毫米来确定 OVD,这一距离即为颌间间隙量。记录的水平颌位关系应为后退接触位。
- Occlusal rims (and wax trial dentures) should only be placed in the mouth long enough to carry out a particular clinical procedure. On removal they should be chilled in a bowl of cold water to avoid distortion
咬合堤(以及蜡试义齿)在口腔中的放置时间应仅足够完成特定的临床操作。取出后应立即浸入冷水中冷却,以防止变形。 - In the mouth the fit and extension of the rim should be checked and modified if necessary to produce acceptable stability.
在口腔中,应检查并调整牙合堤的贴合度和延伸度,以确保其稳定性达到可接受水平。 - The upper occlusal rim should be adjusted so that the occlusal plane is correct in relation to the remaining upper natural teeth. If there is an anterior saddle the rim must indicate the correct incisal level and degree of lip support. Removal of wax from the palatal aspect of this rim might be necessary in order to allow closure of the mandible into the tooth position whilst retaining the incisal level.
上颌咬合堤应调整至咬合平面与剩余上颌天然牙的关系正确。若存在前牙鞍基,咬合堤必须显示正确的切缘高度及唇侧支撑度。必要时需从此堤的腭侧去除蜡材,以便下颌能闭合至牙位,同时保持切缘高度。 - Any occlusal contact (e.g. with an opposing tooth) should be checked when the patient closes with the upper rim in place. If the occlusion shows a premature contact between a tooth and the opposing occlusal rim, the rim should be adjusted accordingly until the occlusal contact is re-established.
当患者戴有上颌蜡堤闭口时,需检查所有咬合接触(如与对颌牙的接触)。若发现牙齿与对颌蜡堤间存在早接触,应相应调整蜡堤直至恢复咬合接触。 - The lower rim should then be adjusted to produce even contact.
下缘应调整至均匀接触。 - The lower rim should then be modified so that there is a small space (about 2-3mm) between the occlusal surface of the rim and the opposing teeth or rim with the mandible in the rest position.
随后应调整下颌蜡堤,使下颌处于休息位时,蜡堤的咬合面与对颌牙或对颌蜡堤之间留有约 2-3 毫米的小间隙。 - The retruded contact position should be recorded using wax or an occlusal registration material such as Bite Registration Paste. Petroleum jelly should be spread thinly over the opposing wax rim to act as a separating medium.
应使用蜡或咬合记录材料(如咬合记录膏)记录后退接触位。需在対颌蜡堤表面薄涂一层凡士林作为分离介质。 - The casts should be placed in occlusion using the occlusal rims and checked to determine that the tooth relationship on the casts is the same as in the mouth. If there is a premature contact between the heels of a cast and the opposing block or cast, this should be eliminated prior to mounting.Correct if necessary.
应使用蜡堤将模型置于咬合状态并检查,确保模型上的牙齿关系与口腔内一致。若发现模型底座与对颌蜡块或模型间存在早接触,需在模型上架前消除该干扰,必要时进行校正。
Second Category 第二类
- The rims should be trimmed until the natural occlusal contact is observed.
需修整蜡堤直至观察到自然牙的咬合接触。 - The occlusal contact should be checked with the natural teeth when the patient occludes with the upper rim in place. If the vertical dimension of occlusion has been increased as a result of a premature contact between a lower tooth and the occlusal rim, the rim should be reduced until the occlusal contact is re-established.
当患者戴上上颌蜡堤进行咬合时,应检查其与自然牙的咬合接触。若因下颌牙齿与蜡堤间早接触导致垂直咬合高度增加,需修整蜡堤直至恢复原有咬合接触。 - The lower rim should be adjusted until there is an even occlusion at the OVD determined by the intercuspal position.
应调整下颌蜡堤,直至在牙尖交错位确定的垂直咬合高度上达到均匀咬合。 - Locating notches should be cut in the upper rim, petroleum jelly applied as a separating medium and the intercuspal position recorded with the rims in place using wax or registration paste.
需在上颌蜡堤刻出定位凹槽,涂抹凡士林作为分离介质,并在蜡堤就位状态下使用蜡或印模膏记录牙尖交错位。 - The casts are placed in occlusion using the occlusal rims and checked to ensure that there is no premature contact between the heels of a cast and the opposing rim or cast.
将模型通过咬合蜡堤置于咬合状态,检查确保模型底座与对颌蜡堤或模型间无早接触。
Laboratory Prescription 技工室处方
- Shade, material and mould of artificial teeth should be specified.
人工牙的色泽、材质和模具应予以明确。 - If the next stage is the try-in of a metal framework, the design should be drawn on the laboratory card and full instructions given. This should be signed by your clinical teacher. The study casts should be retained as a guide for the technician.
如果下一阶段是金属支架的试戴,应在实验室卡片上绘制设计图并提供完整说明。这需要由您的临床导师签字确认。研究模型应保留作为技工的参考。 - If the metal denture is restoring lower free-end saddles consider the need for the altered cast technique. If the technique is to be employed request the addition of acrylic trays to the framework in the saddle areas.
如果金属义齿用于修复下颌游离端鞍基,需考虑采用改良印模技术。若采用该技术,需在鞍基区域的支架上添加丙烯酸树脂托盘。 - If the anterior teeth require metal backings, a wax trial denture should be requested for the next stage so that the appearance and position of the teeth can be approved before the metal framework is constructed.
若前牙需要金属背衬,应在下一阶段要求制作蜡型试戴牙,以便在金属支架制作前确认牙齿的外观和位置。
Master Impressions 主模型印模
· Wax stops should be placed on the fitting surface of the individual trays before modifying the peripheral extension if necessary.
在必要时修改边缘延伸前,应在个别托盘的贴合面上放置蜡止点。

Laboratory Prescription 技工室处方
The laboratory prescription should indicate the material to be used for cast pouring. Bearing in mind that the occlusion has already been determined naturally or by occlusal rims prior to establishing a design, the subsequent stage should be either trial dentures or the production of a metal casting. In the former situation a shade and mould of teeth must be selected.
实验室处方应注明用于模型灌注的材料。需注意的是,在确定设计方案前,咬合关系已通过自然状态或咬合堤确定,后续阶段应为试戴义齿或金属铸件制作。在前一种情况下,必须选择牙齿的颜色和形态。

· If, at this stage, the occlusion is incorrect, modifications must be carried out before continuing with the next stages. An increase in occlusal height may be achieved by adding pink wax to the occlusal surfaces of posterior teeth on one of the dentures. A reduction in occlusal height is achieved by replacing the posterior teeth on one denture with wax rims and adjusting these to occlude evenly at the correct vertical dimension. Wax or bite registration paste may be used for the final recording.
· 若此阶段咬合不正确,必须在继续后续步骤前进行修正。可通过在某一义齿的后牙咬合面添加粉红蜡来增加咬合高度。降低咬合高度则需将一侧义齿的后牙替换为蜡堤,并调整至正确垂直距离下的均匀咬合。最终记录可使用蜡或咬合记录膏完成。
